TIP 1: Don't leave your homework till the last minute. This could really affect the amount of effort you put into it, and what happens if you've got 6 pieces due in the same day, and you ain't done any of them? BIG TROUBLE.
TIP 2: If you're stuck, seek assistance. It's a good idea to ask friends, or the older members of your family, such as older siblings or parents. You could do a bit of research: books, internet etc, which may help. I'm pretty sure it's fine to go to your teacher if you need help, so if you're allowed, pop in the classroom one of the times.
TIP 3: Don't do too much in one day. Seriously guys. It can give you stress, and you might get stuff like headaches. Or, if you're that determined to complete homework, take a break every 30 minutes or so, hopefully resting your brain.
TIP 4: Lost some of your stuff for the homework? If it's something like a sheet, it's best to go to your teacher and ask for another sheet if possible. If it's something like your exercise book, do the homework on a sheet of paper, until you find your book. Pens? Just borrow one from a friend, if you can.
Hopefully this helped. If it didn't, oh well. .-. Leave a comment or a suggestion if you want!
