other possible work to do

I'm not that keen at creating a document that would print this much paper. If anything, we should try our best to reduce paper waste by coding something that makes sense.

The other idea someone suggested was to have it printed with all questions first, all hints and then all solutions.

Nobody wants to waste paper, but I think that nobody would want to print out the whole set all at once... So it really depends who this is targeted for. If it was meant to be printed all at once, that last idea (printing hints and solutions at the back) sounds good.

Not sure what the target really is. We could try to ask students to actually know if we are working towards something that is really useful.

Yeah, I guess once we do the big release announcement (have you done it yet?), we can also do a poll afterwards regarding students' and professors' use of the site.
