1. Hi, I came from Italy and I'll be doing A-levels Maths.
I'd like to know that when there are exam questions if I can use the methods that I was taught in Italy ( which I've realised that are objectively shorter and easier), instead of the ones that are taught in England. (The results are always the same).
2. Hiya! I moved this into the Maths forum for you - you're more likely to get a reply here
3. Depends what type of methods you are talking about. Give me a few examples.

Unless the question specifies a method then any method is allowed. Some questions will be specific about the method they wish to test.
In A level maths, most of the marks are awarded for your working out and you run a risk of not being awarded method marks if you are using unusual methods or short cuts, especially if there are errors in your final answer.
I'd be interested in seeing some worked questions where you utilise these objectively shorter and easier methods.

5. For example to find x in an equation you are taught to use the quadratic formula.
In Italy I was taught (when is ax^2+bx+c a is not 0) to find two numbers that when they add up they give "b" and when they multiply are "ac". Then you have to factorise the equation in 2 separate parts and then you'll find the 2 values of x.

if you get the answer right then i don't see the issue but if you're using all these unexpected methods then you might annoy the examiners
7. Also when you are told to turn a recurring number in a fraction. In England you are taught to use an equation, while by using the method taught in Italy, you can do it by having just a look

Small things like that are forgiven in A-Level. However if you use a formula that is not in the formula booket, you would be expected to derive it, otherwise formula in the booklet can be stated freely. Questions will usually tell you if they want you to use a certain method, though these are mostly uncommon in the Pure and Mechanics side of A-Level.

Factorising is the first method anyone would learn here as well and is definitely an important skill at A level but What do you do when it doesn't factorise? Using the quadratic formula or completing the square are two methods for finding solutions that you need to know.

x^2 -2x -10 = 0

If you are able to turn a recurring decimal into a fraction by just "having a look" that's fine but most people can't do that and benefit from having a method that works. You won't be asked to do this at A level.
