Hello everyone, I'm a current LPN student heading towards the end of 2nd semester, before today I had a Over a 85 overall Med-Surg average, Respiratory have a 90 average and GU I have an 85 average, this is what really kept me above water, on the other hand, I got an 80 and an 81 on two GI test and got a 78:unsure: on the last one, I put soo much time into studying the last GI chapter and it still wasn't enough. That in turn brought my overall average Med-surg average down to an 82. Now I really have to do well on this final exam, and I'm only gonna have the weekend and Monday to do it. How can I do it? Any advice/strategies would be greatly appreciated. Thanks
