From the look of the question I'm guessing you're quite early on in your studies.
If you are thinking about a career in law then the best favour you can do yourself is to actually do the work yourself and learn something to give yourself a chance at being any good at the potential career choices at the end of your studies.
Believe me, the basics like contract and general legal principles really do count, both in later studies - if you don't even know the basics, how are you ever going to understand enough to expland on the and use them in a practical sense.
Regardless, your answers need to be targetted to the course you are doing eg law degree is very very different to law school and you approach things in a very different way, same as in practice.
If you're struggling with a particular concept then people may be more willing to help out that just posting an entire question and hoping someone will do your work for you.
What if people on here are wrong? I see wrong answers often. Are you going to use it as an excuse that you failed that someone gave you the wrong answer on a public website?
It's also possible that people will give you practical advice when what your studies require is an academic perspective.
Accountability is one big thing in practice.
If you were advising a client, would you google the answer to a serious issue?
