Welcome to pprune young man, you will get good advice on here.
There always seems to be a lot to do while learning but it will all become second nature after a while.
Stay cool, when I was learning, at the moment when I was starting to concentrate like starting a descent, my instructor would hand me a boiled sweet, "Fancy a sweet Mart?" he used to say while I was thinking that I had more pressing things to think about.
If you read 'Home is the Hunter' the author experienced an instructor who put a burning match in front if his face while he was fully engaged. (have I got the name of the book right guys?)
