True, but at NATS and the college, the decision of whether or not to get an approach ticket as well as an aerodrome ticket isn't your choice.
Instructors may think you're well suited to approach, or there's a big need for people with that ticket for either TC or regional airports - you can express your preference not to go on the approach course, but definitely no guarantees! There's been several people recently who've wanted to go to London airports but ended up on the approach course and are headed elsewhere now...
