I think I would just summarise my education, so for example 'my qualifications include X GCSE's, X A Levels and then in blah blah I completed a degree in this subject'
To me personal profile sounds like talking about all of your skills and strengths that you have developed in previous roles or that you naturally have. Then I would talk about strengths and skills I have that are really specific to the job, linking them to the role where possible.
Skills are things that you have learned how to do, that you will use in the job. Whereas strengths are things that are inherent to your personality that you never learned which will be useful e.g. being a nitpicking perfectionist.
Duplication is good. Remember the person who reads this isn't going to be reading it carefully like you do. They will be skim-reading whilst trying to get through a stack of 40 applications when they only have an hour, and pulling out 10 or fewer that are most promising to read more closely and select the 4 they want to interview.
If you only mention each good thing about you once, the chances are that you will come across as half as good as you actually are.
Well I only have 4 GCSEs at C grade - but a degree and a masters so I personally wouldn't assume anything. I have been declined for a job which wanted a B in math despite said masters ( qualm and quant subject) and seriously relevant work experience. But the B was important to them.
