Does a gap boost chances at Undergraduate?

If I do a gap year and get A*A*A* in my A-Levels will they ignore my GCSEs?

A gap year will have no impact on your entry. I would actively encourage taking a gap year. It gives you a chance to experience the real world outside education and find out about who you really are.

Yeah lucky for me my parents don't mind me doing a gap year. It puts less pressure on getting university offers

Maybe. University isn't the be all and end all and frankly if you are only going because that is what you do, on a life long scale you will find it pretty pointless. Much better work out what the goal is and if that involves uni then go for it. Otherwise hold off and wait. You only have one funded shot at uni. Don't waste it.

It depends on the subject. Some universities for some subjects specifically encourage or discourage gap years. For Maths, for example, some places discourage them unless you can specifically show that you've kept up your Maths during your gap year, e.g. with tutoring, learning more Maths, etc. ; whereas for Engineering, some places actively encourage gap years if you can get relevant work experience etc. during that time.

I was planning on doing a maths degree, so if I don't get offers this year should I just do tutoring in my gap year?

Not necessarily tutoring, that was just an example, though that could be helpful. The main thing that they are concerned about is that your potentially going rusty over the gap year.
I did extra further maths modules, STEP and tutoring in my gap year, all of which seemed to help.

Which year are you in? Predictions are only given in Year 13 - before that they are targets and these are very inflated and unbelievable given your GCSEs

I'm going into year 13. I achieved A*A*A in my year 12 mocks

Predictions should be based on more tha one test. If you are still at the same underperforming school they will be unbelievable ...
Gap years for Maths aren't advised
[So were you truthful about being 16 on your other thread if you are going into Year 13?]

I 'made' (past tense) that money at 16

And the other points?

I personally would work for myself, I am only getting degree as it shows credibility.

Ah right. So that isn't about you. It is about them and the fact they only really care about students who are going to maintain the reputation of the university. Do you really want to study somewhere that cares more about its own image than the learning of the students who come through the door?
