Yeah, I've got a rather busy week ahead of me. There are two lectures on Tuesday. One is a chemistry lecture at 10 a.m. and the other's a pronunciation lecture at 2 p.m. The pronunciation lecture goes for one hour and then it's followed immediately by a plant pathology lab. Well, actually, Wednesday's my busiest day. I've got two tutorials, a lecture and a physics lab. The lab's the first thing in the morning at 9 a.m. That goes until 11 a.m. Then, my first tutorial, which is plant pathology, is at 12:00 p.m. I get a couple of hours' break for lunch and relaxation. Then at 3 p.m., I've got another tutorial--my microbology tutorial. That goes for two hours. Finally, at 5 p.m., I've got my genetics lecture. I've nothing on Thursday, thankfully. And Friday's a short day. I've just got a lecture--plant pathology. And the best thing is that it begins at 10 in the morning. So from 11 o'clock, I'm free to enjoy the weekend!
