What is NTA?

What is NTA?

On November 10, 2017, it was announced that the Cabinet approves setting up of National Testing Agency (NTA), a body to hold all such exams which CBSE and AICTE conduct until now. Under its umbrella, JEE also falls.

Will JEE 2019 be conducted by NTA?

Maybe. There is no clarification as to from which year NTA will take over CBSE’s responsibilities for the JEE exam. The changeover was not done in 2018, and there are talks of JEE 2019 being conducted by NTA. MCI/MHRD or some official body will clarify the same.

Should students be worried?

Worried – no. Prepared – yes.

You see, the official notice about NTA says “The entrance examinations will be conducted in online mode at least twice a year.” This would be a major change in JEE 2019 if NTA decides to conduct JEE 2019.

So to be prepared for such an event, start attempting JEE mock tests in online mode.

Thanking You..

Aman Goel Journey To IIT

This has been shared by Aman Goel.

Here is how it was for me:

• UKG to class 5th: studied in an okayish English medium school in Kanpur. Used to rank among top 10 in class. Screwed up a couple of times, but was doing well. Elder sister used to teach me. I was not at all a studious guy. I rather spent most of my day playing cricket and other games/sports with my friends.
• Class 6th - class 7th: school was changed to one of the best schools in Kanpur. Rank fell down from single digit to double digits. Percentage went down from 90+ to ~70. Didn’t care at all. Wasn’t a studious guy. The teachers in school and the residents of my society were so fed-up of me that my parents wanted to send me to hostel. I used to fight with my sister when she taught me. Enjoyed life like crazy. Played a lot of games. Broke some people’s heads. Messed up with teachers. Fought with classmates. I arguably had the best childhood.
• Class 8th - class 10th: sister got married when I was in class 8th. Responsibility of studying suddenly fell on me. Class teacher was fed-up with complaints against me. I used to spend most of my time either outside my class (due to a punishment) or on the floor of the class (again, due to a punishment) :P. She made me sit with the most sincere guy (call him A) in the class. We became good friends and the “peer group” effect started to impact me. I started becoming serious about my studies. By class 9th, I was among the toppers. It was 2010 and A’s brother had secured AIR 125 in IIT-JEE 2010 (now JEE Advanced). In 10th standard, the school took us on a visit to IIT Kanpur. Mesmerized by the beauty of campus, I made my mind that some day I will also come here. I became extremely serious in class 10th and I studied a lot. Ended up topping the school with 97.4% marks.
• Class 11th: started JEE preparation with the big dream of cracking IIT Kanpur. Got to know about IIT Bombay CSE from my class 11th Physics teacher. Learnt that only top 100 rankers are able to crack it (that was back in 2011 when the cutoff was around AIR 75). Changed the goal to a top 100 rank + IITB CSE. Performed well during class 11th, but still, I was not even close to a top 100 ranker’s performance.
• Class 12th (May 2012 - September 2012): got in touch with Manoj Sir - the teacher who changed the way I saw Physics. He taught me how to hit Physics problems with the most fundamental concepts rather than applying end-results/formulae. I applied his ideas not just in Physics, but also in Chemistry and Maths. This started producing good results and eventually I became extremely serious about JEE preparation.
• Class 12th (October 2012 - April 2013): FIITJEE AITS (test series) started. I performed well at the national level (1 and 2 digit ranks), but the scores were low because AITS is extremely tough. My ego got hit and I studied like crazy during these months. Maintained a top 50 rank in AITS consistently.
• April 2013 (the JEE Main time): Did well in the exam. 300+ was sure. 323/360 was icing on the cake. Cracked INPhO and INChO also.
• April 2013 - May 2013: Worked like crazy during this period. It was clear by this time that if I don’t screw up JEE and perform as I have been doing in AITS, a top 50 rank is sure.
• 2nd June 2013: screwed up JEE due to a sudden change in pattern.
• 3rd June 2013: got to know that it isn’t just me who screwed up. Relative performance was great and as per FIITJEE’s calculations I was getting a top 50 rank.
• 21st June 2013: JEE results were announced, AIR 33 in JEE Advanced 2013.
• Counseling time: I filled 9 choices in the following order: IITB CS, IITD CS, IITK CS, IITB Elec, IITD Elec, IITK Elec, IITB Mech, IITD Mech, IITK Mech. I knew that under any circumstances, I am getting IITB CS (there were 43 general category seats at that time), but my mom was slightly paranoid and she made me fill so many choices. :P
• Counseling results: was partying with friends when results were declared. Cracked IITB CSE :)

Kalpit Veerwal Success Mantra

This has been shared by Kalpit Veerwal.

Let's have a look:-

“ I have been wanting to answer this for a while. So here it goes.

I started studying for JEE specifically since class 11, but my preparation for the world of competition had started in class 7 itself. I used to score well in all exams in school, and used to study extra curricular stuff too. So one fine day, I decided to open the class 9 textbook of my elder brother. I could understand stuff written in it. I got lost into studies.

The same continued till middle of class 12. In these 4–5 years the only thing I did was to study. I studied in classes 9–10 for IJSO, In class 10 for NTSE, RMO, NSEP and for more knoweledge in general. I used to study some class 12 stuff too in 10th itself( maybe not JEE level, but I knew things).

I did not go to any class picnics, never went out with friends(had few of them), left all cultural and sports activities, didn’t watch TV or Movies( no interest anyways at that time), thinking it would ruin my academics. I started listening to Linkin Park in class 10 and it continued till 11th. It was the only thing I did other than studying( and a little bit of cricket at home). I enjoyed it, so won’t say I wasted my childhood. This had a good end after all.

In 11th and 12th I became even more determined to perform and learn more. I even used to study in my school bus. I spent all time studying. I couldn’t clear INPhO in 11th and was a bit low as similar thing happened in class 10( missed NSEP by 2 marks, and cleared cutoff of all states except Rajasthan).

I was a bit research oriented and used to study lots of stuff apart from syllabus specially in Physics. I decided to focus on JEE after my INPhO failure. My performance in Resonance tests was good but I could improve.

Then came the most important time of my life, class 12.

I was seriously into JEE now and started to study even more. But then I got little distracted in 12th. I started watching Harry Potter again after 6 years( accidentally turned to HBO). I became a fan, started to read novels, started listening to even more music( Coldplay). A few other thing too. I got a chance to go to Coldplay’s concert in Mumbai( my brother won tickets), but didn’t go due to my zeal and commitment to my studies(felt bad after watching it on TV).

Course ended. Holidays declared. Lots to study, specially class 12 material, as I focused less on new topics towards the end of 12th. But I also started watching TV, as I used to be alone and got bored easily. Time flew, boards came, and went. Couldn’t clear INPhO this year too, due to mistakes. I missed both INPhO and INChO by narrow margins(cleared INAO though with a good score). Meanwhile, I began to realize how that I should have studied more in holidays. There are only few people I talked to- my two best friends , and my brother. Talked to them and realized no more time to waste. This was around March 2017.

Four days left in JEE(Main). I was one of the best performers from Udaipur , so people expected more from me. I called my sir and told him about the time I had wasted in holidays . I told him that I won’t perform well in JEE(Main). He motivated me a lot and said that I had been working hard for years. A few months don't matter. And I too thought that I was overestimating my time waste. I was still studying a lot.

2 April came. I said to myself, and so did my parents and teachers, that I will perform my best without thinking of the score. Went in. At a point, I was like I would not even score 300. But then I remembered sir’s words and started back. All I remember is that by the time the bell rang, I had attempted all the question( the same as my coaching tests).

Came home and checked my score to be 350/360 from Resonance key. I was happy and determined to score well in Advanced too. Started studying a lot and cleared all backlogs. Then the official key came and I was scoring full( expected it after seeing Resonance key). Before JEE(Main) result, round 1 of JEE(Advanced) was over.

Then came the result of JEE(Main) . I tried not to get affected from it. My teachers and parents helped me in this. I studied really hard for Advanced. Was fully prepared. My teachers and family helped me a lot.

Reached the venue on 21 May, 2017. All told me not to expect anything. I didn’t myself either. Gave paper and came home. I felt I had done well. Was scoring around 300/366 . I was happy about it, although I had made many ’silly’ mistakes.

Then came the result of Advanced. I expected a rank in top 50 based on my score, but the statistics were very bad this year. Got AIR 109. Still was happy about it. Many people called me and asked why did I score this ‘bad’ after topping Main. I guess only those who have given JEE can understand it( how even one question can afffect your rank). Anyways, I am not going to say that my rank was so and so due to so and so reasons. I accept it the way it is.

This was my story.”

Thank You:)

How many times jee main can be written ?

You can attempt at JEE Mains three times. Once while appearing for your 12th board or other qualifying exam and two more times after passing 12th or the qualifying exam. But do note that the 2 attempts need to be in consecutive years right after your 12th. Hence the JEE Mains 2018 can be attempted only by those students who are presently appearing for boards in 2018 or those who have passed the board in 2017 or 2016 only.

All the very best and good luck:)

Is it necessary to give improvement in all five subject for JEE ADVANCE 2018 to overcome 75%.

1. 
   
2. 
   
3. Candidates who appeared in Class XII (or equivalent) examination for the first time in 2017 and wish to (or have to) reappear in 2018 with the objective to qualify through top 20 percentile cut-off criteria, should reappear in all the subjects. For such candidates, top 20 percentile cut-off for 2018 will be considered.
4. If a candidate has passed his/her Class XII (or equivalent) in 2017 and wishes to improve his/her aggregate marks to meet the “aggregate marks of 75% (or 65% for SC, ST and PwD) criterion”, he/she can reappear for any number of subjects he/she wishes for improvement. The percentage marks in this situation will be calculated by considering the marks obtained in 2017 or 2018, whichever is higher, in the respective subjects, in his/her two attempts in 2017 and 2018.
5. All The Best...

How do IITJEE toppers prepare for each chapter and what is their strategy?

This is what IIT JEE toppers do,

1. They follow a disciplined strategy. They love the subjects they are studying.
2. They know their strengths and also work on weaker areas.
3. They focus on concepts understanding and application of logic. When starting a topic, he/she would make sure to study all the related concepts at once and then solve the problems.
4. Go into the root of the problem, understand the concepts instead of memorizing them (some exception to Chemistry).
5. Resolve your doubts quickly. If you don’t understand anything, ask the same question again and again from your teacher. Never procrastinate in your IIT JEE preparation.
6. They focus on quality over quantity.

All The Very Best and Good Luck :)

Is it true that MCQs will be replaced by short answers in JEE Advanced from 2018?

                                          

• It's fixed from 2018 JEE will be online.
• As per the rotation rule JEE advanced 2018 should be conducted by IIT Kanpur.
• Please be clear that no decision has yet been taken on introduction of short answer questions in JEE Advanced.
• One aspects which differentiate JEE from any other competitive exam is it's pattern, so don't expect instead accept.
• To address the fear or difficulties with accessing computers which rural candidates may have in taking the test online, JAB has set up a sub-committee to explore options of holding mock exams a week before the actual test so that rural candidates get acquainted with the new test pattern.
• It has been proposed that if necessary, these candidates from villages and rural areas will be allowed to appear in mock tests at the selected exam venues. The sub-committee will be set up under the guidance of IIT Kanpur, which will conduct the next IIT-JEE (Advanced).
• Till this year, examinees were allowed to take a copy of the optical response sheets back home as proof of their appearance in the exam. From next year, the computer will record the responses and a soft copy will be mailed to each candidate's registered email.
• Clear all your concepts, you will perform well irrespective of new rules.

ALL THE BEST....

Can we use Facebook during IIT preparation or not?

Avoid smartphones, social media, and relationships - these are the three biggest distractions at this phase. Avoid all three as much as you can.

Multitasking is appreciated, but it might prove costly during JEE preparation. JEE is not about mugging up the topics, hence train yourself to stay focused and do only one thing while studying – just STUDY.

All The Very Best and Good Luck :)

What is the last rank in the JEE advanced good enough to take admission? I think after 5000 you get useless branches. Is that correct?

Not at all,

Even if you end up with a relatively bad rank, you can opt for branches like Bio technology and somehow get into IIT. Work hard for 1 year and you can as well change your branch depending on your grades.

These branches also provide you with lot’s of course flexibility and you can as well do your minor in other streams of Engineering. You can use IIT tag to get into MBA or PHD later. Surely, there are lot of perks of being a part of top IIT.

Apart from IITs there are several institute which fill their seats on the basis of Jee Advanced ranks.

Hence, you can even get an admission into top institute with JEE rank under AIR 4000.

All The Very Best and Good Luck :)
