I'm studying A level biology and chemistry there at the minute. Due to finish in June! (hopefully)
The Titanic Quarter is 'alright'. Be prepared in winter though, it gets hellish windy!
Titanic Quarter building is all very posh and fancy, however last year (the first year the building was open) the roof blew off and they have a leaky window on the ground floor corridor towards the exam hall.
Due to the building being rented now, Belfast Met requires 'all' the classrooms to be in use all times during the day. Because of this, especially for A Levels I don't know about HND, the classes are at very funny times during the day. However, HND you'd be studying a lot more so the class times shouldn't be as random.
The tutors at tech are 50/50 chance of getting a good one. I was very lucky.
Beware of the college system called 'Blackboard'. It goes down regularly at the most inappropriate times and therefore you can't get to your college email. Email coursework in as soon as possible, because it'll go down just at the deadline.
If tutors are off sick they probably won't email you. So you have to make your way in to find out.
Canteen food is alright if not overpriced. 80p for a very small cup of tea. They do toast and breakfast which is good.
Library is alright. It's on two floors. There is a small 'quiet study' room with Macs.
Students Union is pretty poor I think. They do a few clubs like LGBT and Christian club and a few sports clubs.
There is a tannoy system which is highly annoying during class.
Titanic Quarter station is about a 5-10 minute walk away. Belfast City center is about 15 minutes. Odyssey Arena that has food shops is about 5 minutes down the road. The buses come every half an hour or 20 minutes.
This is all about the Titanic Quarter. I don't know about the other campuses.
My opinion: It's alright but frankly I dread going in everyday and I don't hang about long so I can leave as soon as possible after class. But other people tend to really enjoy the place.
