Lakes training is difficult because they don't care if you succeed. They won't go the extra mile for you and you'll get the bare minimum that is needed to succeed. It's up to you to put forth effort to make it through training. Lakes also expects a lot. They are very through and in-depth on systems, limitations, regulations and operations etc. They will not hand feed you this information, it's up to you to learn it and know it!
As I've said before you'll leave Lakes a very good pilot and everywhere else you go training will be a breeze!
OO.
