I'm not sure but I think I'd prefer colleges over international schools if I want to study A-Level.

As for which institution, it depends on a lot of things like how far it is from your place of stay (or you want to live in in-campus / off-campus accommodations), the course fees, etc.

Sunway and Taylor's are pretty good in terms of A-Level in KL / Selangor, but of course they're more expensive than the others. I studied my A-Level at UCSI and I felt satisfied. My lecturers were good and my Maths lecturer is at Sunway now. I heard MCKL is a good choice as well but I'm not sure.

Oh I forgot to mention that I went to UCSI University KL Campus, not the college. The college at Damansara Utama should also be offering A-Level according to this.

The fee should be the same 'cause it's the same for me as well. Don't really know how it's like in UCSI Colleges.

30+ min of travelling time should be fine. It's all up to you whether you're okay or not. Do remember to take traffic jams into consideration.

Not sure about INTEC. By the way, oops, seems like MCKL is not a good choice. I forgot about TAR UC which I think is fine as well and it's even cheaper than UCSI, but I don't know much about INTI.

However, if you really have the money and can afford, then Sunway or Taylor's. If not, then you can try the other institutions all of us listed here like UCSI, TAR UC, INTEC, INTI, etc.

INTEC is RM ±40k, which is also the same as GMI's German A-Level (GAPP). I think the only one more expensive than Taylor's is KYUEM in KL / Selangor.

I think it's still possible for you to get scholarships/bursaries since you still have 5A's in your SPM nonetheless. Just try to apply.
