Gcse predictions good enough for investment banking?

Hello i have received my gcse predictions and i have tried hard this year , too hard to say the least . I am hoping to be a investment banker if i get my correct grades for my a levels and following it up to uni..
Anyway these are my predictions i feel they are not strong enough simply because of science.
Btec science : Distinction
Maths : A
English language : C
English literature : B
R.e : A
I.t : Merit
Food technology : B
Computing ( Already done ) : B
Business studies ( already done ) : C

This thread makes me so sad.

Focus on maths and computer science, become decently good and you should have a decent chance of algorithmic trading. A lot of other forms of investment banking are dying or dead because computers have become better at investing than humans in most short-term investments. Make sure you know what within investment banking you want to do and why (if it's just "money lol" give up now), and work really hard to make sure you get better GCSEs than those (if you work hard and can't do better than that at GCSE, you won't do well enough at A Level and more education simply won't be for you). For when you pick A Levels, economics is more suited to the job than business studies, the latter being a bit of a joke, but both are kind of boring IMO. I can't remember which one's which out of IT and computing but you want something that's closer to computer science. Do maths AND further maths, and ideally focus on decision maths and statistics as opposed to mechanics.
