I was petrified of microbiology and it ended up being one of my favorite classes. Med surg can be a hard class for some people there is some memorization involved and a lot of nursing process involved. What I did in med surg was I always read ahead of class, taped the lecture, rewrote notes, and used some NCLEX study books to help me get used to the questions I might get on a test. If I did not understand something I would google it from reputable websites and having another source explain it helped. Youtube has some amazing videos on diabetes, hypertension, etc that helps. Math and I also are not friends it takes me longer to get it than other classmates but I have never had problems passing med math tests. There are some good websites out there that are helpful. Some of my classmates also have math for dumbies books that they swear by. Just remember that everyone does math differently and uses a different way to solve the problem find a way that works for you and stick to it. Best wishes next semester!
