Can I get into uni with 2 btecs?

Hi, I'm going to sixth form in September this year. I was homeschooled in Yr 9 so I don't have any gcses but I do have maths and english functional skills. The only problem is sixth form won't let me do a levels, only applied generals. So I was planning on doing a criminology level 3 (worth 1 a level) and a national diploma in H&SC (worth 2 a levels). But then someone I know told me u can only get into uni with a btec extended diploma worth 3 a levels. They said that national diplomas and extended certificates have to be grouped with actual a levels to get into uni. Idk if that's true so I was wondering if it is. I would rlly like to go to uni and study criminology or something related to that. This probably made no sense so apologies if it doesnt.

The advice you've been given is misleading. For some universities and/or some courses, you'd be expected to have an A level or two alongside any "vocational" qualifications like BTECs and Applied Generals. However, that doesn't apply to every course at every university.
Did you have any universities in mind as places you'd like to study? Any university which specifies it's entry requirements in terms of UCAS points is likely to be fine.

Im interested in Hull uni, Leeds beckett or York st John. I'm pretty sure for criminology at Hull it's 112 UCAS points but I'm not quite sure on the others so I'd have to check. Thanks for your advice!

Correct. For Criminology, Hull want 112 UCAS points (source), as does Leeds Becket (source). York St John want 104 points (source). All three will be happy with your combination of qualifications.

Great thankyou!

Which jobs do a criminology degree lead to? I think you need to know the answer to that question before you decide on the university? If a criminology degree does not actually lead to any jobs what are you going to do after the degree course? Would you be better doing an apprenticeship that does lead to a job?
