For Mina:
Your main problem is that you think that you’ll get a low average and you want to pass BAC exam again to study an appropriate specialty. Ok; Pass BAC as many times you want as I explained to our sister Amany. For the idea of (Bloquer) the administration won’t accept it unless you give them a logic justification.
I think that you should wait for the results and see which specialty suits you; a specialty that seems helpful which will be your career in the future. In case you couldn’t find the specialty you’re looking for choose something else study it; in the same time sign for another BAC exam to get a high average that allows you to choose your desired studies. It doesn’t matter that you will lose one year; the problem is that you’ll regret if you spend 3 or 5 years studying the wrong specialty.
By the way can I know what do you want to study in the university? are you on literary stream or scientific stream?
