how to do assertion and reasoning questions in AIIMS really

For attempting assertion and reason u must have really strong concepts and must know all the theory of each topic atleast of ncert .....
U should read all the chapters line by line and understand every concept and underlying reason ...
And practice a lots of questions . We get confused a lot in option 1 and 2 because it's really hard to think whether or not the statement given is reason of the first . so for that practice a lot and read carefully that's really important and for aiims assertion reason constitute lots of marks it's 60 I guess and that's really a lot ...
Let me know if u need any other help.....
