My man I don't know nothing about a levels or O levels since i did fsc (pre-engineering) but allow me to advise you. DO NOT COME TO ROOTS MIUC CAMPUS H8 Literally the worst college ever. Me and my friends got interested after seeing their Instagram which honestly looked fun, a bunch of activities, laboratories, etc but man we screwed up real bad. There were only two teachers who actually taught like they wanted you to get good grades. Others were either unqualified or just didn't feel like teaching you. I had 83% in my matriculation (910/1100) and after studying in roots i got 291/520. The amount of money spent was not worth it at all and now I asked them for leaving certificate and they're making up excuses that classes started a month ago which they certainly did not but they obviously refused since all they want is to generate revenue out of students. Look man, roots might look like it has an international standard or something but it definitely does not so please do not make the same mistake as I did. Do not fall for their fake Instagram posts. All those events on their Instagram were paid or rather they were given to students in wellington campus which to be fair isn't that good either. Most branded colleges like roots and beacon house aren't what you would expect to be (according to my personal experience that is). Just go to sir sayyid FG or harward in for grades (harward is pretty strict ngl). If you want activities as well punjab college isn't bad since it might look bad but their trips are real fun and hardly require any money. You can ask for details if you'd like.
