what are the tips for preparation of neet medical exam ?A person learn not even one question? How can you suggest that type of people?

@ divya 
dnt think like that , u dnt knw any single ques , by this your will power to crack neet will be degraded and that is what most imp to crack this exam . 
so, if u havenot started preparation yet and gng to attend neet in 2017 , then just start by the previous year paper now , 
and by this time , focus more on biology ( 11^th ) and as 12^th bio are very very easy , so, retaining 11^th portion will be difficult . 
bio contains 50 percent of ques and have a good weightage , , and after that focus on chemistry easy chapter like electrochemi , surface chemistry , equilibrium , thermo ,  neet asks very simple ques from it and make sure u not leave anything from this chap . 
and in phy , the difficult one u can elave , but take a look at the current electricity , semiconducter , modern physics , and a little bit abt capacitors . 
they are very very imp and make sure u did all ques from previous 5 years paper . 
ALL THE BEST ..
