Don't do a fourth, it's useless and will take time away from studying for the other 3. Universities literally ignore the 4th A level so I don't understand why people waste time doing it.
Regarding EPQ, don't do it.. Also waste of time lool. All/most unis mention on their requirements, *not including General students or EPQ*.
Don't even get me started on the clowns on TSR who ask if they should do 5,😂😂😂
