well if you hire someone to do your homework they won't go with you when you take tests.
not real sure what their intention is but am sure it is help the student learn not to do all thinking for them.
I do know this forum does not want to do homework outright
they just want you to post a couple problems show some of work and and then ask where you are stuck.
also, I have seen people post take home tests, but these are usually always detected and no one offers help.
I have visited other forums, this one seems to have a very high average expert level.
