@Dody if that’s of interest to you, and if you wanted to do something similar to GUE fundies is that you could contact a tech instructor and literally pay for their time to have a 1 to 1 session (or couple of sessions) without a class but just you defining your goals: for example improving your finning or buoyancy.
Of course you’d have to choose the right instructor.
I did this with a TDI instructor and that was very useful for me.
