It doesn’t really matter too much - it’ll just mean you get emails targeted to the level of student that you are. After putting my grades in there, I got 10+ emails a day from Universities (almost all ones I had zero interest in). They mainly had advertising, with the occasional fee-waived application.

I’d say try and find an equivalent grade, but don’t worry too much about it being 100% accurate.

Awesome thank you! It’s quite a hassle to sit there and enter your years and grades for each subjects haha

No worries, I definitely agree!
