What grants are available if I am studying a part time higher education course?
Assuming you live in England, then you have access to a tuition fee loan. There are no grants available, although part-time students will probably be entitled to part time maintenance loans from next year.
Well, the government was planning on extending maintenance loans to part-time students from 2018 (and 2019 for Open University students)... but there's a new government, so it remains to be seen if it will still happen. Just have to wait and see.
