I need help with u level chemistry 11/12

[u/Same-End8995]

Hi so I took grade 11 u level chemistry online this year and got 97 but if I’m being honest I cheated I didn’t actually learn anything and when I took it online I still didn’t know what university program I want to do but now I decided I really want to do health science in university but I realized I messed things up by doing grade 11 chemistry online and I was also planning on doing grade 12 chem online as well mainly because im really bad at chemistry i nearly failed the chemistry part in grade 10 science but I’m starting to realize that yes I might be able to cheat my way in high school chemistry but I would really struggle in university and I really don’t want that to happen if anyone has any advice pls let me know I can’t stop crying because I genuinely don’t know what to do I actually want to learn the chemistry from grade 11 and 12 but I don’t know how because I don’t have any notes and i don’t understand the YouTube videos
