In JEE January 2020 application, should I enter Class 12 Passed/Passing Year as 2019 or 2020? I have passed Class 12 with 66% in 2019. I have to appear for Improvement to fulfill eligibility. So should I select 2019 (as I passed last year) or 2020 (since Im appearing for Improvement this year)?

Murali PT 17th Sep, 2019

Hii..

As mentioned that you pass to your class 12th in year 2019 with 66 percentile and you appear for improvement exam in 2020 ...

so you should mention the date of passing class 12th  as 2019 as by giving improvement exam its not giving you a passing certificate so you get your passing certificate after passing class 12th  in  year 2019 ..so you have to mention the 2019 as the passing date inner JEE main application form..

All the best!!

what should me the min marks in jee mains to get iiit delhi according to new pattern

Paras Khurana 17th Sep, 2019

Hello Paras

Sorry to misinterpret IIITD with IITD. With the Introduction  of new pattern you must get a rank under 10k. As you know the cutoff changes every year but a rank under 8.5 to 9.k can fetch you IIITD. Also there is CSAB so you can give a try.

Sorry again man.

I m not clear cbse 12 boards exam in 2019 due to some reason and my result was failed and I clear my 12cbse boards exam in2020 .May i applicable for jee mains in 2020???

Shreya Mishra 16th Sep, 2019

Do not get demotivated by your failure. Failures are the part of success. Learn from this failure and dedicate yourself to crack the IIT JEE exam.

For being eligible for JEE Mains 2020,then you have to pass the 12th exam which you will be giving in 2020. You not only have to pass it,but have to score more than 75%. Then only you will be eligible to make your dream come true.

Other than this, I will suggest you to fill the form of NIOS (National Institute of Open Science). This exam is equivalent to your board exams and the best thing about this is you can give exam at anytime of the year. Score well in this exam and you will be eligible for the JEE Mains exam.

Feel free to ask me in the comment box if you are having any further doubts

hope you find it helpful

Good Luck!

vetenary course without jee for non medical.

Ritesh 16th Sep, 2019
Hello there!
Greetings!
First of all , if you are a non-medical science  student then you are not eligible for veterinary course. As to be eligible for veterinary, you need to have biology in your class 12th and if you don't have it then, I am sorry but you cannot go for veterinary.
And coming to jee , then it's not jee which is required for doing veterinary, one needs to go for exams like neet to get a seat in veterinary college.
Thankyou
Good luck

How to Do preparation of JEE Main for Board(11&12) Students?

Dharmik 16th Sep, 2019

Juggling between JEE Mains and Board Exams is quite a task in itself. With almost all exams having a cut off on your 12th board percentage, board exams can’t be underestimated anymore. Almost all board exams start in March while JEE mains starts in April which means you have to plan your JEE Mains and Board Exams preparation extremely meticulously. Here are some tips, which you should keep in mind before you get started with JEE Mains and Board Exams:

JEE Mains and Board Exams

1. Focus on concepts & theory

While JEE Main is about practice, board exams are about theory. You have to be at articulating the theory and concepts you have learnt rather than applying them across many questions. Until you have a good grasp on theory & concepts you can do well while practicing for JEE Main. You would be tested heavily on theory and hence this provides a great opportunity for you to get well versed with it and brush up some concepts in more detail as it would ultimately help you in JEE Main as well

2. Revise thoroughly

In board exams, revision is the key to scoring marks. Its also important for JEE Main that you remember all the formulae so that you don’t miss on the easy questions. There are some aspects in each subject which need to be learnt by heart and revising it thoroughly can help you fetch easy marks. If you have a time constraint, prioritize the chapters with maximum weightage in JEE Main, which you have already covered and make sure that you revise them.

3. Have a Plan

Before you put pen to paper have a goal and plan in mind. Strategy is key to competitive exams’ preparation like JEE Main. Use the time for preparing for board exams to optimize your JEE Main preparation. A structured and detailed plan will not just help you focus but will also enable you to see the entire syllabus in one go and then break it down piece by piece. Here, you should be extremely careful not to exaggerate your abilities to complete topics. Be very practical and create a plan accordingly that satisfies boards as well as JEE Main preparations. Trying to do too much will stress you and disappoint you because it is not possible to work all day continuously without rest.

Include breaks, naps, and snacks in your plan as well so that you replenish your body from time to time.

4. Complete the Syllabus

Make it a point to go through the entire syllabus thoroughly without missing out on any topic. Many students tend to leave out topics because they think they are too easy or too difficult or because they barely have time. Start your preparation early so that you have time to complete the syllabus. JEE Main has questions from all the topics. Make sure you touch every aspect of the syllabus regardless of what you think about them (easy or difficult). This approach will help you ace your boards as well as your JEE Main exam because you will have studied everything clearly.

5. Understand the pattern

Having a thorough understanding of the question paper pattern is a must. JEE Main follows specific paper patterns that can be understood & strategically used to score well. This will help you study because you will know how to break time down and how to prepare for the test. Note the differences between the board exam paper pattern and the IIT pattern. Do not get confused between the two.

6. Avoid comparison

Do not compare your board exam preparation with your JEE Main preparation. In fact, you shouldn’t compare any aspect of these exams. Use the time during board exam preparation to optimize your JEE Main preparation but do not keep comparing the exams at every step. This will lead to confusion.

7. Practice Previous Year Papers

Practice previous year test papers of JEE Main will help you polish concepts that you are not confident about and get into the real groove of the JEE Main. According to the results, enhance your study process to help yourself further. Alongside, do not miss out on previous year board exam papers so that you work on both hand in hand.

8. Take up a Test Series

Studying with the help of a test series will also help you focus, understand your weak points, and augment your studying methodology accordingly. The Internet has many test series that you can make use of for board and JEE Main preparation.
