feel a bit stress ....

It 18th June and i still got one exam paper on 21th june and the other on 23th June. I can feel a bit stress now, but was veri lazy in studying. Think i get a pass grade is enough but will feel gulity if i dun put in effort to get a better grade. I think i just put in some effort ba. i had obtained abt 29/35 marks for the paper on 21th june , need abt 21/65 marks to pass. For the 23 june paper , i obtained abt 43.8/50 marks, think need 1.2/50 to get a conditional pass or 6.2/50 to get a pass grade. So i think the issue is not on passing , it on if i want to get a better grade or not ?? Wish me good luck and hope i pass or get a better grade ..... and faster go back sg enjoy my life like a king , wo ha ha ha .......
