Please take my tone being of one of complete sincerity. What exactly do you want to get out of a recreational wreck diving course? How do you think it will improve your skillset and/or give you knowledge allowing you to do a different category of dives?
These are conversations I like to have with potential students. Let's take navigation as an example. It should be more than following a compass but also the student should acquire a feel to how slopes and current impact the heading one takes. With how slopes can have an effect, try swimming a triangle pattern where there's a "reasonable" slope. It isn't easy to get back to the starting point which is one reason why I use it in courses. The same thing with current. It is very hard to determine how much you need to compensate for swimming underwater towards a target when dealing with current.
Same thing with buoyancy. These sorts of questions need to be answered to ensure you are getting the minimum value you require for your time and money.
For deep courses, there's nothing to going to a greater depth, but there is a requirement for improved situational awareness, acknowledging the impedance from narcosis that is exacerbated by gas density (a must to be discussed but missing from deep diving course materials:
Performance Under Pressure), and emergency management.
I hope I'm not going off into the weeds but giving you something to think about that you will use to your benefit as you move forward with your training.
Good luck!
