On Question asked by student community
Hello Alka
For JEE Advance, the best 5 subjects through which you need to calculate your percentage is:
1. Physics
2. Chemistry
3. Mathematics
4. One language (which is English)
5. One other subject of your choice
So you will need to choose PCM + English + a 5th subject to calculate your percentage.
Hope this answer helps! Thank You!!!
Hello!
In JEE Advanced eligibility, the top 5 subjects from your board exam are considered. Usually, they are Physics, Chemistry, Mathematics, and any two other subjects from the main curriculum. If CMS is your optional subject and IT is an additional subject, the board will still calculate based on the 5 highest marks from your eligible subjects. Additional subjects are considered only if they replace a lower score from another subject. For example, if IT has a higher score than English or CMS, then IT can be counted. However, some boards follow strict rules where only main subjects are counted, so you must verify with your board’s official notification. The 75% criteria means your average percentage in those best 5 subjects must meet the requirement. My advice—list all your subjects, arrange them from highest to lowest marks, and take the top five as per rules.
Hope this clears your doubt!
Getting under AIR 100 in JEE Advanced in 6 months is very tough but possible if you already have strong basics and are scoring high in JEE Main-level tests. You'll need 10–12 hours of focused daily study, advanced problem-solving, and regular mock tests. If you're starting from scratch, it's unlikely, but you can still aim for a good IIT rank with consistent effort.
Hello,
To qualify for the JEE Advanced, you need to score a certain percentile or above. This percentile may change depending on those years competition. Generally you need a percentile of 93-94 to qualify for the JEE Advanced. So, every year only 250,000 candidates from the JEE Mains out of all candidates qualify for the JEE Advanced exam.
I hope it resolves your query!!
