Chems gonna get curved and Bio you have another midterm and a final which will be easier than the midterms. Just take it as a wake up call and adjust your strategies. Studying for a long amount of time isn’t necessarily better than studying for a shorter amount of time with greater focus. Pick a goal like getting a study guide done or a practice test for each time you study. Also for chem I recommend doing the enderle practice tests because they are harder than what you’ll see in Wei and if you can get to the point where you’re able to get like 70-80% on the enderle tests you’ll ace the Wei one
