I would concur with the wise words above. For most of my 28 years flying I have been of the opinion that anything you can do to make your life as a flying training student easier is a bonus.
Capacity and rate of learning are crucial.
Having your checks firmly squared away is one less thing to worry about and should help you to perform with confidence which in turn helps to create a decent impression on the simple soul that is the QHI/QFI who, being better disposed towards you, is more inclined to impart some of his/her pearls of wisdom instead of smacking you round the back of the head while simultaneosly using words that would be banned from this forum!!
Good Luck FP
