In my opinion my essay skills in Legal Studies aren't very good, I'm mostly lost with them and what I should be writing, do you think getting a tutor would teach me how to write better essays? Or are they better used for other aspects?
If you feel like your skills aren't quite up to scratch, then definitely a tutor would help you with that! It's about knowing how much help you need. If you are having serious issues with your content, and really aren't understanding how to translate it to an essay, then absolutely a tutor would be really beneficial for you.
Usually though, the content isn't going to be the hassle, and essay writing is a skill best learned. You might just need someone to spend 2 hours with once a month or so, or even just Skype sessions here or there. If you are confident with the content and just need to develop essay writing skills, then the weekly sessions might not be the best use of time. Sometimes the Maths students I tutor ask for 30 minutes out of their session now and again to chat about their essays for English and Legal, and usually that is enough.
So if you think you just need some guidance, a little bit of oversight, and someone to bounce ideas off of - A weekly session might not be the best use of time. You could be better off just doing less frequent sessions, or even just using the forums. We answer questions, we mark essays - We're like the tutor you'll never pay for
But if you think you would benefit with the time on a regular basis, and can find a good tutor who will fill the time with good exercises and things to make the time beneficial, then absolutely it would be a great thing for you!
