As for the all-changing in mid-sep.... HA! You'll only be doing about 18 hours a week

First year uni is lovely stuff.
Some of us were getting an average of..ooo...one hour a week in summer term of second year

(Having said that, for that amount of contact time, you have to work your arse off...well, ish....an essay a week is probably an extra 12-15 hours....)
