Mocks objective is :
1. Build confidence
2. Analysis
3. Learn from your mistakes
4. Identify bottle necks
5. Most imp: Dont take score to your heart/head.
I think you are missing out on practice especially via sectional tests to consolidate your strengths in quant and DI. Also, keep modifying your overall strategy after you have gone through a rigorous mock analysis.
Practice will again make you cross 90 and dont worry so much as its a long battle and dont let it get 2 u.
All the best.
