First, they need to assess which teachers "Don't mind" if you don't do the homework. This could mean they stand you up in front of the whole class and shout at you, but if they don't give you an after school detention, don't do it. Getting in the teachers good books previously helps with this.
Second, if you've got a joke subject before one with homework due, do the homework then. Geography before Maths for example.
Third, have a homework team where you take it in turns to do the easily copied homework (Maths, DT, Science) and then copy each other in the mornings before school. Of course you need to cover your tracks.
Fourth, always cut corners. No calculator? Lol, use a calculator, but purposely get a few wrong. Use Google for everything (I didn't have a computer until yr8). Never read a book when you can read a synopsis/ watch the film whilst playing Pokémon.
Fifth, work as a team at home. The parent will have to remember things from their childhood, where as older siblings only need to remember from the year before. I used to do my middle brother's compulsory homework, whilst he did my littlest brother's, and my mum did mine.
Other tricks: Try leaving all of you books related to that subject at home one day and claim you thought it was Thursday.
Miss out a question at the bottom of a page, they might not even notice.
Pretend you are/were ill.
Cry
Hand in last weeks homework again. This one only buys you time, but works well on a Friday.
Tell your teacher you'll hand it in tomorrow, then the next day tell them you handed it in yesterday and they've lost it.
Band together with the other kids in your class and tell the teacher they said the homework was due for next week, or that they didn't even set it.
If you are asked to hand something in on lined paper, just don't do a whole sheets worth. More convincing if both sheets start/end in the middle of a sentence. I've done this before and they didn't even comment, I suspect they felt guilty they'd lost it.
Note: I successfully used all these tricks on several occasions. I would say that it definitely had no impact on my education (Got a AAAB at A level, 1st Class degree in Electronic Engineering w/ Hons), and a very significant positive impact on my life as a whole.
