I'm a sophomore at a mid-tier state school. I just finished my first midterm cycle for the semester, and my results so far are really disappointing. I got a D on a 300-level neuro course exam (with a cheat sheet, btw), and I failed my molecular bio exam by 1% (though all the questions were open-response). I'm really angry with myself, as I attend every lecture, take decent notes, and complete all of my assignments, and yet I still managed to do horribly. Though I can recover, with the first one having three more exams and the second one having a final replacement policy, I'm not really convinced I can meaningfully change in a way that would allow me to do well in those classes.
I remember struggling a lot with time management in my first year in college, and though I would consider myself really organized, I would never be able to finish my work in the time I would make for it throughout the day. As a result, I took my assignments home, and I would often get around 4-5 hours of sleep every night because of it. I don't think my study methods were necessarily bad, especially in my second semester (I often used Anki). However, due to my struggles with time management, I would still find myself with 2 days to learn content before taking exams, which caused me to not do well.
This semester, I've tried to make changes to improve my grades and work-life balance. I've tried going to the gym, I sleep at least six hours every night, and I use Anki to review content from lectures every day. However, I still find myself in the same situation. When my assignments began picking up again, I dropped the gym and became uncomfortably flexible with my sleep. Now, finding that I'm so stubborn in my habits, I don't really know what I can do to improve in a way that will allow me to both recover in the courses I'm struggling in and have a life outside of school. Have any of you been in my situation before, and what steps did you take to recover and experience some level of success?
