In my experience, BIMM London is below average.
The facilities are great for recording music and practicing. It is a good place to start your music career and to get familiar with the studio environment. The student and networking events are good for meeting people that have similar interests and for collaborative work. Though because of the area , Fulham, these events can be very expensive and not so student friendly. The area is also quite disconnected transport wise.
Student support was very weak, sometimes taking up to 15 days to respond. Also, with the university being so small, it would often get crowded.
Overall the teaching was good in my experience, but there is variety in the quality of learning depending on the teacher.
I wouldn’t recommend BIMM London as the University is lacking in many areas that can spoil the overall experience.
