STEP exams?

I'm a year 13 student and have achieved grades AAA at AS in Maths, Further maths and economics, with over 90% in maths and further maths, I would like to study maths at uni after year 13. I have heard about STEP exams but am not sure, can I sit all three exams, is this extremely difficult, has anyone ever done this, do many people do this? Would 3 S grades in the STEP exams plus A*A*A with A*s in maths and further maths guarantee me a place at Warwick, Imperial or Bath for maths? Feedback would be very much appreciated.

1) Yes, you can sit all three exams.

2) Yes, it is difficult. To put things into perspective, it is approximately the top 2% of A Level Mathematics candidates who sit STEP. Out of those, less than half manage to attain a grade I and less than 10% obtain an S grade in any paper. Simply having A*s and >90% UMS is nowhere near sufficient to do anywhere near well in STEP. It requires significant preparation and demands a much higher ability than A Levels do.

Alternatively, consider the fact that Cambridge require grades of 1 in 2 STEP papers for entry.

3) People certainly have done this; I did for example. Not many people do this however; it is only really people applying for Maths at Cambridge who do all three STEP papers, and even then a relatively small proportion. I am reasonably sure that the number of people who obtain 3 S grades each year does not even reach 3 figures.

4) It would put you in exceedingly good stead for any university mathematics application. I don't know about guarantees though and would not like to say to avoid giving misinformation.

I think that it might be pertinent for you to have a look at some STEP papers though, just so you are aware what you are considering attempting to do.

OK, thanks for the feedback much appreciated. You say you did all three step papers would you mind me asking what grades you achieved and what uni you went to also what a level results you achieved. Also would I be able to achieve s grades through doing most step past papers, would this extra study fit in nicely with my a levels or is it difficult, how did you dons it in terms of content the way questions were written what is the hardest bit about it?
