Any advice

Hi all,

Iam a first semester on nursing school and at this time m so frustrated because I have low grade on my class which is very disturbing, I need 75 percent to get through this class . I still have two more exams to be done , and to get 75percent I can only miss 4questions otherwise I won't be able to pass the class. I didn't do well on last exam , I ran out of time and left 9questions untouched and there were 7 drugs calculation questions I did 6 of them right but I only got graded on three of drugs calculation. Didn't get grade on other three because I had done tht calculations on blank side of questions paper. So do you have any advices , I do not think of withdrawing from course , I feel like I can do it but again it just hits if not or else .....plz plz any suggestions, advices would be appreciated!!!
