Give yourself time to relax and free your mind from worries before your exam starts so you can focus and concentrate on the questions during exam. It wouldn't be good when due to stress you have some sort of mental block during exam and couldn't answer properly. Good luck!
Dear Author Your Vocab Skills are great so I think it's easy to clear that section however I suggest you concentrate on the reading and listening parts for a better score. All the best
