Another semester in  at college

I have been back a week now after our school break/holiday. There are different ways to say this and this is just one example. eg It's been one week since i've been back at school.

for about one week since my last day of holiday and from that I already got a lot of assignments. Although I saw knew these would that it'll be coming, I was surprised that I was going to get got so many assignments this much. I was expecting that I'll to have some time to read or do something besides of what I'm studying at school. I mean these assignments takes up so much of my time, but it's okay actually lol. I just feel like I should do something about my time management, so that I can do have both of a school life and my social life. It's ironic that I'm studying about management (economy, human resources, accountancy, etc) but I can't manage my time management well. lol I'm bad.
any tips for this?
anyway please correct me if there's any mistakes in my writing (ofc there'll be lots of it).

ps: I was writing this while doing my assignment LOL (ain't anybody cares though)

All the best Gillian
