Should i keep trying parallel reasoning?

No matter what i do i cannot consistently get pr questions right more than half the time. Im sure if i keep at it, i will improve but that wont make me efficient. I find that if i guess blindly i save 2 minutes minimum and make fewer mistakes on the last page using that extra time. My current method is to see if the prompt either results in x=y or x≠y and eliminate all the answer choices that dont match. After that i take a blind guess which is about 1/3 chance. The extra time i save from this is never enough to go back to the question so i usually review other questionable guesses in my exam. Should I keep using this method for the February exam?
