@ xavier
actually the thing is frst complete the syllabus . thats the frst thing u have to do , and make sure u have not leaved any topic behind , which will trouble you in jee advanced .
and after that start with previous year papers , as they are vvimp catagory . and start that from mains level , dnt atrget advanced at frst .
and after solving 5-6 years of jee main ques start with advanced , at frst u will feel uncomfortable but beleive me , donot loose hope .
and after doing 5 years jee adv papers , switch to mock test of askiitian or u can take sample paper .
and remember – not to repeat the mistake , anytime .
and learn from each and evry mistake .
and do practice 2 mock test everyday , 2 month prior to jee main exam . u are done with .
ALL THE BEST ..
