I dont know
Welcome to the BB forum. You sound like you've done so well... Finding a direction/goal/dream to strive for. Well done! And I think you're doing the right thing reaching out for help here and at uni. Honestly, some teachers/lecturers are not very good at teaching, or not very good at helping when someone asks for help. It sounds like that might be the case with yours... It's great that you're reaching out to Student Wellbeing. Hopefully they'll have some ideas about how to get more assistance with the math. A tutor, or a peer study group might help.
Also, I reckon there will be other students struggling but they are hiding it because they're worried about looking silly... It's such a shame that we're all too scared to admit when we're struggling, so we suffer in silence. Anyway, I reckon it's great that you are asking for help.
Thinking of you, Ebi
