Agr rc timer s krti hu toh accuracy nahi aati hai aur agr Bina timer s karti hu toh accuracy aati kya karu ??

Try to solve with timer onlyy. Give yourself 10 mins for each RC and then analyse where you are going wrong, and the practice and improve accordingly. With regular practice you can reduce your time and improve accuracy per RC.

timer only, analyze it later, eventually you will improve
