Sociology 101 is on there, Monday at 3.00p.m. There is only one Sociology lecture a week, plus a seminar, which will be arranged when you arrive. (I know this because I did Sociology Part 1)
Your Biology class is a Part 2 course, and the Part 2 timetable is still being constructed, so it might be some time before you get the details.
Your classes are a bit unusual in that you are taking a mix of Part 1 and Part 2, presumably because of what you have already done in the States.
Hope this helps. Don't panic, Lancaster are a bit dis-organised at times, but they always get there in the end!
