Dear Aspirant,

You've picked the right thing for the purpose of your situation -"analysis of mock". Now see completing syllabus is just one of the things to be done for exam. But you should analyze what are your weakness, what portion of the syllabus are you facing difficult, are there any mistakes which are being repeated, also are there any questions which could've have been done but got wrong / were not attempted due to conceptual clarity, also did you spend more time on any question than it should be given. Noting down mistakes after every test might help. Also for Maths theory part should be crystal clear to solve problems, and obviously practice is most important along with time management in maths.
