Luckily, my Mother knows how to do CVs and has to go through them every now and then.
My advice is to try and sell yourself to whoever you're trying to convince you have the right qualifications. Tell them your strong points, what you're capable with, your weaknesses. That's what I had to do, and always do several CVs, never just stick with one, do more. So that way, you can decide which one sounds more powerful and will hook in the person so they'll apply you for the job/education.
I might be wrong on some parts, if so I'm sorry.
