Firstly a university degree is very important for finding a a good job

because it would give you an advantage over someone without a degree.

On top of that, studying a degree will also provide you with social skills

'Not only that'

'on top of that' and 'in addition to that' are better phrases to use then

'furthermore' and 'moreover' that many other students to use

On top of that, studying a degree will also provide you with social skills

I believe this is true, because...

When you're backing up your points

you could say 'I think this is true, because' or 'I believe this is correct, because'

always think of good reasons to back up your points

and above all, say it like you mean it and believe in it. Peace out.
