I recently got a drysuit 50/50, sent it to dui and got the seals fixed. I have not taken my drysuit course yet. I took it in the pool and was trying to get all the air out of the chest area, as it balloons up even though i tried to burp it by holding the neck seal open. I opened the purge valve all the way. I then started to hold down the exaust valve to get all the air out in the water. Is it normal for some water to seep in when holding the exhaust valve all the way down under water? If it is a little big in the chest, will wearing a bigger undergarment help?

Did you turn so your left shoulder was UP?
You will learn that the worst position (aside from full inverted) is upright.... Get horizontal, and lift your arm above you to vent (make sure the valve open) through the shoulder/bicep dump - it is an automatic valve. No need to push to deflate...
I will add that the open/closed position on the valve is dictated on the water temps. If really cold water, I will carry extra weight which I then offset with more air to make the insulation work. I then have the auto valve closed to hold the air, and use the push to release air. When going up the line, I will open the valve to auto dump. If moderate temps, I dive the valve fully open.
YMMV.

I don't believe I've ever had water seep in from being pressed. Mine used to leak just a hair when in the fully open position. I took it apart and stretched the spring a little and it's good now.
Why do you say this? Just curious. I dive horizontal, but sometimes end up upright on the line or something, never really had an issue unless there's an excessive amount of air in the suit.

the low profile apeks has a reputation for being somewhat leaky if left fully open, i generally will leave it only 80 percent open. never had an issue with sitech.
Being vertical can result in air burping through the neck seal, which can result in water pouring in.
I was thinking that myself about the accursed Apeks low profile valve.
This:
as well as a tight squeeze to an undesirable location below.... can be quite uncomfortable (to me anyway)....
YMMV
