I joined TV and Radio specifically for the radio aspect, and was annoyed that I had to wait until January to start it. I feel like for the TV aspect I did not learn anything I didn't learn in college (i did a media btec) and the teachers didn't properly teach us how to use the equipment before sending us out to film. Most of this course has been me teaching myself how to do stuff rather than them teaching me.
The course in a whole is good but you have a lot of free time to self study. In the first year it is very basic but in second and third year you get to choose which subjects you would like to do so you can really tailor your education to you dependant what your future prospects are in terms of life and jobs.
