how to improve my accuracy in RC?

24 days streak in daily rcs, earlier it used to take me 10minutes+ to solve 1 rc, i tried to improve and now my avg time is under 8minutes and i think this is okay for now and I want to improve my accuracy now! my overall avg is 17 and i want to immprove that, my biggest problem is when i get confused in two very close options. How to tackle such questions? and any advice how could i improve. thank you!
