On the first day everyone just starting out got advice from those that already went through the first 3 weeks.
I liked a lot of the advice. I haven't followed some of it.
Sleep (I haven't done that enough.)
Ask for help
Don't be afraid if you have to repeat phases.
Take notes (I have done this. You forget by the end of the day let alone future days.)
Don't code all the time; spend time doing your former hobbies.
Don't stay too late (I can't so I haven't done that.)
Go drinking with your classmates. I agree with the hanging out with classmates part. The drinking part isn't necessary.
Some advice I didn't care for was the advice to take your shoes off and relax. So many people walk around in socks or barefoot. I don't know how they do that. I need my shoes. I guess in general telling people to relax and not stress is a good plan.
I'm surprised nobody gave a warning about the chairs that sit on the floor. I really hate those.
We got tips from about 30 people but now that it's been 2 weeks I forget the rest. This has been open on my computer for awhile. I figure I should post it even if I did want to include more originally.
