Give me a heads up of what to come?

I am thinking of
choosing these subjects for ALevel:
Maths & Statistics
Maths & Mechanics
Further maths
Physics
Psychology
Economics

I'm currently in year 11, and college/6th form is
coming up fast and i want to know what is
expected from these subjects and are they
helpful to get into universities that specialize in
economics e.g. LSE. Also can you give your
opinion about these subjects.

(I am already doing Maths and Statistics in Year
11 since i have already achieved A* in maths in
year 10 but i would like some advice)

Well done on your A*
For economics, I think it would be more helpful to have Maths and Statistics.

Your other subjects are good Personally, I find Mechanics easier than Stats as it's less tedious. Physics is ok bit of mechanics in here too. I don't know enough about the others to give you an opinion sadly.
