what happens if a student....

a bit more info please, what options are you choosing and who were the staff that told you it wasnt for you (were they head of year, teacher tutor)? as i cant say much without knowing?

the options i chose:
Option One: Health & Social Care (Level 3 Applied)
Option Two: English Literature
Option Three: Economics
Reserve Option: Sociology
i got told by my sixth form interviewer and the raising achievement staff member in my year team

Don't know anything about option 1.
English Lit will require you to be very good at memorising as many exam boards (from what I have seen) seem to want you to memorise poems and compare them. Don't know how good you are at this but its something to think about.
Economics is also very maths intensive so if your really struggling with maths I would advice against it. If you enjoy business studies (if you ever studied that) then its probably a good choice.

doesn't do well in sixth form
- i've been told by two staff members that i might not get into sixth form
- and i also got told by siblings that i'm making it hard for myself with the options i chose
- i dont like the idea that its harder than gsces
- and i'm feeling under pressure with having to do well in the exams
