@ raghav
The Jee syllabus are mainly based upon the cbse syllabus of class 11th and 12th ..
and hardly there are any question came from class 9 and 10 ,
and its related to foundation .
so, in class 9 and 10 , u need to focus upon trigonometry , gravitation part , carbon and its compound ,
behaviour of solid , liquid and gas . etc .
for jee questions u might refer to some FOUNDATION COURSES AT ASKIITIAN ,THEY WILL HELP U .
JEE DOESNOT ASK ANY DIRECT QUESTION FROM CLASS 9 AND 10 ,
IF IT WILL ASK , THEN IT MUST BE AN INTERLINKED CONCEPT .
AND FOR THAT U NEED TO KEEP YOUR FOUNDATION STRONG IN 9TH AND 10TH ..
the 3 equation of motion are also very very imp , and thats in class 9 physics .
HOPE IT CLEARS YOUR DOUBT
ALL THE BEST ..
