Do my high school marks matter?

[Personherebb9]

I'm currently busy with my Final (NSC) high school examinations and will be done in roughly three weeks. If I'm being honest I've been so distracted with completing college courses and creating a degree plan that I've barely been studying. Nor do I have the motivation to study if I'm being honest. My question is will TESU look at my Final marks, or will they just care to see that I'm the equivalent to a high school grad? Also will I need to send in my high school transcripts to an evaluation service in order to apply to TESU, or will my College RA credits suffice?

I've been holding around an 87% average this year; here are my subjects (English Home Language, Afrikaans Home Language, Maths Core (equivalent to upper level math/AP Math), Life Orientation, Tourism, Physical Sciences (combined physics and chem) and Biology.) But since I haven't been studying I expect that mark to drop SIGNIFICANTLY. Like at least to around 60%. The thing about South African education is that our final exams at the end of the year is weighted at 75% of our year mark. Meaning even if you got 100% on every single exam and assignment the entire year, you could still fail simply if you fail your final.

Since I'm doing RA credits through Metropolia and XAMK, I'll be sending in my evaluated transcripts from them with my application, but will I need to send in my high school transcripts in as well for evaluation? And if I do, could TESU reject me for underperforming in finals. I've been kind of betting on the fact that I'll get in 100% for university so my high school marks don't matter, but maybe TESU does care about that sort of thing?

Any advice would be great thank you.
