New theory:
Your DM is not as experienced as he lead you to believe. He is embarrassed to admit it. He tries to compensate by creating tough encounters and he tries to seem "smart" by pretending he planned in advance for everything you might do - but is really making it up on the fly. His lack of rules knowledge compounds this because the stuff he's making up doesn't actually work.
Why don't you volunteer to run a second campaign in alternate sessions? Then you can take time during your sessions to consult the rules as necessary and make sure everyone is on the same page. Make some encounters that are really easy and don't be embarrassed when the PCs destroy them. Maybe he will understand that learning the rules as you go is ok and that not every encounter has to prove the DM's genius. He will also learn some rules as you explore them during your sessions.
