Biomedical science

I am doing biomedical science degree and it’s my first year. I think I am finding it really hard to manage and get good marks. I was just wondering if anyone who has done this course or is in their 2nd/3rd year could offer some help and advise? It would be really helpful as it’s been stressing me out and I don’t know what I can do to get better marks. As in I try to do best in my assignments but don’t really get good marks....any suggestions? Due to this I have been feeling very depressed and anxious as I don’t want to fail this year plz 😭😭😭

Thank you very much for your reply. Yeah I am gonna try to make notes after every lecture, I didn’t do that. My modules include: core biochemistry, human physiology with pharmacology, molecular biology and genetics, practical and transferable skills. This is my semester B btw, I just about passed my semester A. I did very well in my A levels but uni is not going right for me. I feel like I’ve lost motivation and really cannot figure out how I can do well in Uni like I did in my A levels. Also, I am not used to writing assignments as sixth form was totally exam based. So currently, I am writing a lab report on this Bradford assay practical that we did. And I don’t not know how to actually do it😭 like from the previous assignments that I have done I always loose marks from the referencing and got about 50/60%. I want to get at least 70% and above. Plz, could you help me with this report? As in what shall I include in my discussion. It would be very helpful if you could guide me as this is my first lab report and I want to do well.
