My attempt rate in quant is sticking to 4-5 questions. How to improve upon speed in quant?

find the topic in which you're spending more than 300 secs, and look at the average time taken by others to solve the same question, target those topics or concepts specifically, you'll see results.

Sort the questions in three baskets- low , moderate, high level of difficulty. Spot the low hanging fruits and cover them in first round. also let go of your ego while you get stuck in a question
