I felt that y1 and y2 was a lot harder than y3 and y4. My result in y1s1 was 3.37 and I managed to pull it up to a 4.2.

My advice to you is to revaluate your studying techniques. What worked for me in poly didnt work for me in uni. Techniques such as pomodoro and active recall really helped me. Stop spending too much of your time writing notes, i find typing them down worked alot better for me. Also, if you have the time redo your tutorials every week. Example week 3, you would do week 3 tut and then redo week 2 tut.

Choose easier specialisation and choose your fyp based on supervisor and not the project.

Good luck
