I’ve been through the police academy twice. It was the same academy but almost 10 years apart so things weren’t exactly the same. With this wealth of information one of the best tips I can give is to keep your mouth shut and pay attention. The only other important piece of information is to work hard, don’t give up and take it all seriously. If you are told to walk a certain way (never carry anything in your gun hand) or you have to button your coat up all the same, do it. I could go on, don’t wear your watch to PT. Be on time for everything. Bring everything you are told to bring. Don’t try to cut corner or be lazy. This goes for academics or practical exercises.
