I have only 90 percentileand around 25 day left what is the easy way to get maximum score in chemistry and other...?

Hello,

You didn't mention the exam you are asking about but according to the 90 percentile thing i assume it to be JEE Mains.

As per NTA, JEE Mains which was to be held between 6-10 April has been postponed due to COVID-19. The new dates will be released by NTA on or after 31st March.

You scored 90 percentile in January session. For January Session around 935000 students appeared. So your rank will be somewhere around 93000 - 95000.

To score good you can take help of this JEE Knockout Package by clicking at this link - https://learn.careers360.com/knockoutfull-jee-main-january/?icn=jee-main-knockout-moneyback&ici=clevertap-sticky-exam-web

It offers unlimited mock test, previous year papers and doubt clearing by experts.

Apart from this try to revise all the topics. Don't start anything new but work on your weaker sections. Practise as many mock test as possible and also solve previous year JEE Papers as this will help you understand the pattern of exam. For Chemistry Mug up all the intext questions and exercises from NCERT because sometimes direct questions are asked in Chemistry from NCERT that too especially in Organic Part.

Hope this was helpful.

Good Luck!
