Ds goes to a grammar school, he needs high marks to get into the sixth form. (He may or may not get the grades...he's border line at present)
There is a sixth form nearby and a college too.
His choice 1 is his school sixth form to do a levels.
Choice 2 at the moment is the other sixth form with slightly lower grades required for a levels.
Choice 3 he has mentioned 2 t-level courses at the college which he likes the look of.
Do people usually apply to multiple courses and then decide once GCSE results are out?
When I was applied for college back in the dark ages I just applied for one course and my GCSE results determined the course level.
