eyes wide open

have a paper to take tomorrow morning. done all the sample exam papers provided in the course notes. gone through them over and over now. not sure of what to do next.
the good news is it's an open book exam. whatever i've done and copied down can be brought in and be used as referral. feeling kinda nervous now and can't sleep. always happen everytime i'm taking a paper since taking up this part time course.
anyway, pray for me. will do my best tomorrow.
