JEE Main comes every year amid a lot of talk and furor. This year, it has been the same. It was conducted between January 8 and January 12 in two shifts. A total of 11,09,250 candidates registered (9,29,198 for Paper-I & 1,80,052 for Paper II) for JEE Main 2019. The national testing agency (NTA) conducted JEE Main in fully computer-based test mode (CBT) for the very first time. Students will also get another chance to appear for JEE Main 2019 in April.

The candidates, who will qualify JEE Main, will be eligible for appearing in JEE Advanced 2019, which is the next level for admissions to Indian Institute of Technology (IITs). Only candidates who will qualify JEE Advanced 2019 will be shortlisted for final admissions to IITs. However, the successful candidates of JEE Main 2019 can take admission in different NITs, GFTIs and IIITs.

**The winning ratio**

There are 24,000 seats in all in the National Institutes of Technology, Indian Institutes of Information Technology and other government-funded technical institutes. 12,00,000 youngsters sit for the exam. For every 50 students, one will get a desirable seat. With these odds at stake, the pressure that can haunt a student before the second attempt can be unmanageable.

**How to evaluate the score:**

In case you have appeared for JEE Main this year, and are confused about the score, you must know about the percentage and percentile. A percentage is simply a representation of a proportion out of 100. To say three out of every six is the same, or to say fifty out of every hundred, in other words, fifty per cent. On the other hand, a percentile is a statistical measure of distribution. For a given set of data, it is the level below which a certain percentage of the data falls.

Percentile scores are based on the relative performance of all those candidates who appear for the examination. It is obtained after transforming the scores into a scale ranging from 100 to 0 for each session of examinees.

Percentile scores indicate the percentage of candidates who have scored equal to or below a particular percentile in an exam. It is the normalised score and not the raw scores. After normalisation, each topper of a session will get the same percentile of 100, which is the desirable one. Also, the marks between the lowest and highest scores are also converted to the respective percentiles.

The formula used is - number of candidates appeared in the session with a raw score equal to or less than the candidate divided by the total number of students appeared into 100.

The rank calculated is (100- NTA percentile score ) X no of students appeared / 100. If NTA percentile score is 90.70, JEE Main rank will be (100-90.70 ) X 874469/100 = 81325. Now, this becomes a dampener owing to the increasing number of students taking the exam.

NTA has announced that normalisation will be session wise, so the percentile score you got would be relative to the others in your session. This score denotes the percentage of candidates who have scored equal to or below (same or lower raw scores) in that particular percentile in that examination.

**Learn from your previous score:**

National Testing Agency (NTA) declared JEE Main 2019 result for January session on January 19. Now, the question arises, whether to go in for the April 2019 exam. The answer is 'yes'. If you appear in both exams i.e. January and April, then the percentile score for both exams will be compared. The highest percentile will be considered. If you appear in one, the final result will be based on that attempt only.

**Revise your strategy**

You need to have a bi-forked strategy this time - one to revamp your preparation and two to work on the strategy on the day of the exam. It is certainly believed that when you prepare for the second attempt to take the exam, you can adopt better strategies needed for preparation. This will help you increase your chances of clearing the entrance exam in comparison to your first attempt. Besides this, in the second attempt, you can secure a better rank as well.

It will be useful if you first analyse the chapters that you want to concentrate on. You will understand the dos and don'ts after the first attempt. You can tackle the problems in the most efficient way by the method of study adopted.

**Time to relax**

On the exam day, you must remember that you have done everything you could have. Try and relax by reading newspaper or magazines etc. Go for a walk in the evening before the exam but avoid eating outside. Stay healthy as this also contributes towards your performance. Another thought that worries every student on the exam day is about how stiff the competition is. It cannot be predicted whether you will make it or not. You should not worry about the topics that you could not do properly. It is best to do revise formulae and scientific names that you have done in the past.

**Know the why**

While we have covered all the hows, we should not forget the importance of your 'why'. The reason why you persevered the last two years is not just to prove that you are better than your peers in physics, chemistry or mathematics; the why is much deeper. It might be the way to your dream university. Once you have your 'why' answered, write it down and go through it before you start your preparation.

**Focus on maths**

While preparing for Math, keep this in mind:

(a) Candidates obtaining higher percentile score in mathematics will get a higher rank.

(b) Candidates obtaining higher percentile score in physics will get a higher rank.

(c) Candidates obtaining higher percentile score in chemistry will get a higher rank.
