Hello Ayushi

As far as IIFT is concerned, I would recommend doing the following -

Pick up past 10 years’ question papers, time yourself and solve them under exam conditions. The quality of questions therein is comparable to nothing else.

Go for either Career Launcher mocks or TIME mocks.

Whichever mocks you pick up, make sure you analyse every question you attempted or you did not attempt. Time management is extremely important in IIFT.
