Note that evacuating air in your feet by lowering feet below horizontal takes longer than many people think (particularly with two layers of socks). Start lowering, wait, then wait a bit longer, then wait again (have a dive plan where you add gas to feet and then move gas around and up to vent, playing with length of time your feet are down to vent). Consider too the thickness of your socks. If feet aren't cold, consider using thinner socks/1 pair (I've had good luck with Fourth Element Artic socks over a very thin pair of performance polypropylene (liner) socks).
Currently, the only reason I am wearing two layers of socks (Specifically an REI liner layer and an REI mid layer) is to fill out a bit of the space in the boot. I don't feel cold.
Yeah, I am struggling with the vent while ascending bit, where you extend one leg, an arm, vent and then go on. That is one of the places where I get dragged up by the feet.
Sounds like instructor may have gotten you to lower your tank. Ask them to check you on land and in the water to see if it needs to be lowered any more. (Given the arch in one's back, a lower tank does not necessarily mean harder to reach valves--too low yes, can't reach, but there is a spot just above this that can be a sweet spot. For some, it looks like this, high (can reach but head hits valves and leads to face plant), lower (hard to reach valves due to curvature of spine), lower still (can now reach valves, then lower (can't reach valves as too low irrespective of spine curvature).
I will bring it up with him. Currently, it is set such that I can do a valve check on the surface (just barely) by moving my hand while stretching. I haven't tried in horizontal trim yet.
With Fundies, great to have time (weeks if not a month or longer) between first two classes and last two classes to sort out your kit and work on establishing what you learned in first two sessions.
Best of luck
The good thing is that I am doing Part 1 and Part 2, so I do have some spacing to come back with more learnings.
