Being unsure about choosing answers.

[Aquamarine]

Whenever I take LR and RC from preptests (esp,LR), sometimes I can't be sure whether I pick the right answer.
When I choose an answer, I think like "Hmm..It looks like it's an answer." or "It might be right." and I choose and then move on to the next question even if I'm not sure about the answer. So half of the answers I choose are usually right and the other half are wrong.
So being unsure about choosing answers always makes me feel really worried and annoyed. Especially, PT50s and recent ones make me feel vulnerable and worried. I want to be sure and certain (e.g Yes, this is an answer!) when I pick answers.
How can I overcome about this problem?

Please someone give me advice.
Thanks!

Ha! Aqua, you're effectively saying, "I get some questions wrong. Please make that stop happening."

There's no answer other than the obvious: keep studying!
