I'll be honest here. I've read the previous posts by you and it seems you just want to take some easy subjects and pass easily.
Like Engraved said : 'Anything worth having means hard work'.
You havent taken math, right ? Then you lack the foundation to do math in A levels hence you can forget about doing an MBA or any Engineering course.
You wanna do well in life you got to work hard and that means taking so-called hard subjects like maths.
