Evening/Weekend course for Higher/Intermediate 2 courses in Glasgow

I am looking to study computing/ IT at college/university as an evening course however I will need to study Intermediate 2 and highers first. I was wondering if anyone knows of any colleges or university in Glasgow that offer evening or weekend courses for Intermediate 2 or highers in either computing, computing science or information systems. I was also wondering if anyone knows of any colleges or universities that would offer intermediate 2 or higher in English on evening or weekends. I also do not mind studying online if that is an option.
