Private Candidate A-LEVEL HELP!

I'm 18 years old, i left school a few years ago now i'm attending my exams as a international private candidate via british council. I need advice on whether i should do my IGCSE's first then do my A-LEVELS or go straight for A-LEVELS? I'm turning 19 this year and don't want to waste more time or money, so i was wondering if i should just do my A-LEVELS directly since IGCSE's alone are considered quite useless. Any advice will be appreciated thanks!

What subjects are you considering doing at A Level? It all depends on how prepared you feel from your previous school experience. If you feel that you'd be prepared to start A Levels straight away, which will definitely be harder without any teachers, go for it! Maybe it would be an idea to have a go at your IGCSE's in one a year to see how you go with that, and if you can do that I bet you'll be ok with A Levels.

so far I'm planning on taking a levels psychology, sociology, english lit. I have studied igcse sociology, english lit, english as first language, biology. But i'm just confused if i should even bother with the igcse's or not since i'll just waste time & money. And how many subjects do i have to take for a-levels? thank you for your reply
