Timetable 1.
Classes are more condensed (less space between them) and you don't always have labs, so your Tuesdays, Wednesdays and Thursdays look really awesome
Keep your chem tutorials + labs together (I think they force you to do that). remember that you can attend other tutorials, not just yours, so just drop in to one of the tutorial times whenever you feel like it.
That being said, this timetable might be problematic for you if you're not a morning person.
