hi there!!!

By this time you all would be wondering why are the method so uncertain.Every problem will have one unique method and how to remember all those during the test...

solution is simple ..

there is no particular solution, you can figure out your own ways to solve it

it can be the traditional way or option check etc etc

and do remember one thing this is not like your normal exams to learn something and present it on a examination day or hope for some repeated questions but just practice hard so that you will be on the same page of the book.

just understand the concepts and few basic relation between them and then try to solve each problem as a challenge.

1 last thing aptitude is a elimination process and not a selection process, so make sure you are better than others :)
