tips for getting a rank

Constant practice & most important - patience.

Revising as & when you do classes during your articleship period.

Rankholders use their study leave to make one day before(exam) notes which is the game changer.

I know some rankers who prepared there own notes for all 8 subjects & revised them as much as possible

It is advisable also to do notes on Excel/Word since you can keep adding/making modifications when you find a new question/concept problems.

Also they usually complete their syllabus once in those 3 years along with their classes.
