Re-start with A-Levels instead of a mixture of vocational courses and AS

I am currently studying a certificate Level 3 in food science and nutrition, a certificate in level 3 business and AS level psychology. After consideration and talking to various people they have said it is unlikely I would get onto a psychology degree course as the first two are A-Level equivalent, more coursework based but I would need to have distinction or higher as they are both marked pass, merit, distinction and distinction* and do not have much relevance to the degree. I therefore am unsure whether starting again completely from scratch would be the best option as from my mock results I only got a pass in food, the teaching is poor currently and nobody seems to understand the course. As well as this there is no textbook so the whole thing is really unclear and then had an A in psychology and a merit in business. Therefore, would you recommend starting again with 4 A levels. If I do I would choose psychology, sociology, business studies (actual A-Level) and English language at a college where they do A-Levels. I am happy to start again and even though I want to do a psychology degree I am unsure about doing it alongside business or sociology so I would study a joint honours degree and doing an actual A-Level in business and sociology will help me choose as my current business course is very much coursework based and very little theory so I think it is unclear whether I would want to study this in the future at the moment from doing just this course. Thanks for reading ! If you can give me any advice that would be great, thank you
