Hi,

The syllabus consists of 12th class physics, chemistry and maths along with English and current affairs . The exam is comparatively easier as you will already familiar with the subject in your boards. Also incase,  If you have prepared for JEE Mains, no matter you cracked it or not, and or you got more than 60 % marksin your  boards, then you can easily crackit and get good rank.  Just brush up your basics and revise the topics before the exam.
