It really depends on how competitive your course is. Normally, if you are very close to your offer grades (AAB) you can still get accepted. Last year quite a few students were accepted even though they missed their grades by a bit. ABB is probably a bit too lenient but you never know. Safest bet though is to aim for AAA or higher bc it’s still very possible that if you miss the grades even by a bit you won’t be accepted.
