It looks fine
The only thing that will suck, is having physics lab and chem lab back-to-back in 2nd term...especially if you're in a slower physics group that runs late. My friend had physics lab and bio lab back-to-bad like that, and she hated it and was always late for bio lab, even though they were in the same building. I'd also recommend against having a Friday 2:30-5:30 lab (so whatever you do, don't put your chem lab there unless you absolutely have to!!!). I had it every other week all year this year, and it was AWFUL. I'll also have it every week next term, and it sucks because you just want to be done the week/go home/go out with people, but you can't because you have a lab.
