Yes, but not exactly 'repeat' in the same way
- Repeat englang and actually do work
- Repeat methods if get <40, starting exams from the beginning.
- Biology and put heaps of effort in
All at TAFE and then heaps of free time to play, work and have fun~
(as i've said so many times)
It wouldn't be that bad at all, but it would be absolutely horribly to repeat it at school i personally believe.
For me that (i'd probably end up just doing two, depends though) is a semi-gap year

Oh and, there is pretty much no point in repeating if your scores are too low for a non-specialised degree as transfers are possible and there are other options. So pretty much only ever agree with someone to repeat if it was for Med, and possibly dent&law.
