Yea, why over-stress over the exams -- not like you get low results means you die forever right? Why become nerd over some stupid exam that's not even gonna make a lot of difference to your life. Relax, and I (dont blame me however if things come out wrong)believe that any of us can do better without stressing ourselves. So don't study today, tomorrow or the day after tomorrow. Relax because you've done your best.
Best of luck everyone!
