Agree with fifi, there is a demand for that.
It's kinda unethical...
Usually I'll just stay back in school, join in some
meetings and offer some advice to the group and their
report
It is not 'kinda' unethical. It is 'totally' unethical.
It is really too much of a slippery slope to condone this thing.
First you start with several cheaters. Then if they go unpunished,
the other honest students will realize that their hard work counts
for sh*t. They then have no incentive to do their work honestly,
and will similarly cheat.
Then when they go into society, they bring their cheating habits
with them.
