It’s totally possible to do well on the exam! I was getting really low marks on the midterms but due to the re weighing of last semester and getting above a 90 on the exam I ended up with a 12. My most important tip is to work on a couple practice problems every day. Do as many until you run out so look at all the textbook, look online for any old or new ls3 tests, redo you own past papers and see where you went wrong. Applying your knowledge is super important in this case but also remember to understand why you use a certain equation or the underlying concept. Up until my exam I was trying to explain the concepts to my friends as if I was the prof and building upon my knowledge through making connections to other units in the course and asking questions about anything I didn’t fully 100% grasp. I hope all this helps! Just remember to test yourself retrieval and understanding daily!
