It doesn't matter if you have a tutorial straight after the lecture, unless you think you can't concentrate for 2 hours straight (with a 10 minute gap).
As for Lecture-Tute-Lab, bear in mind this is at least 4 hours in a row of classes. That's actually not so bad, but if they're all for the same subject you might want to think carefully about it.
It's still okay, but you have to be sure you'll like the subject.
Minai - you should be able to make it from one end to the other in 10 minutes, what are you talking about? Or is that the problem, that you're talking
