Desecent rate
I saw lots of people using far too much time calculating an probable descent rate for NDB
The simplest way is halve the expected groundspeed. 180 knots become 900 fpm 140 knots = 700 and so on. Of course you will have to modify that on the actual approach according to situation but it is a good start
The less you have to think the more brain cells you have left over for flying
You have the right attitude to training, try hard, absorb as much advice as you can from the available areas
Best of luck, you will love the job
