I am a final year undergrad at a tier 1 college in India.

I have solved 400+ leetcode questions. I have given 8 contests and recently my ranks in contests have started to improve (last contest it was around 700 which is an improvement from my average 2k ranks).

I have observed that during mocks, I highly underperform. Usually I know the solutions and I am able to solve the harder questions with ease, but during the mocks, i somehow screw things up.

With the possibilty of campanies conducting coding tests for placement anytime within 2-3 weeks, I am feeling really dejected with my result in mocks.

Should I solve more topic wise questions or should I go for random questions. With just weeks left, I am very confused.

Any suggestion/advice will be greatly appreciated.

Thank You in advance.
