The traditional route to university is to take 3 or more A Levels. Your final A Level grades will give you access to a range of degree level courses. A Levels can transfer into UCAS points which act as entry requirements for universities.
You can study for an A Level at any age, you don’t have to be school or college age. Studying for your A Levels with Open Study College means you can gain your qualifications without having to attend a college or sixth form. You still get the support of an expert tutor, but this route will allow you to take the next steps to get to university without having to give up work or family commitments.
