Can anyone help me how to prepare quant I don't know whenever I solve questions my answer is wrong some time I solved and sometime I don't have any clue I don't know I always get scared of quant pleas

I feel the same, but practice and bring consistent and sitting with the questions will only help. When you find yourself clueless, try once again, then see the solution and see how the question approaches itself. And what's happening - gradual practice will definitely give results.

My personal strategy is to,
Watch videos - understand concepts
Start with easy questions
Then gradually increase the level.

I hope this helps.
All the best! ☺️

Don't be scared of Quantmost aspirants struggle initially, and it improves with consistent practice.
Focus on one topic at a time, solve easy questions first, and analyze every mistake instead of rushing to the next problem.
Accuracy and confidence come gradually, so be patient and practice regularly rather than trying to solve everything at once.
