Single mum, studying/funding , benefits and childcare

[DollFace13]

Hiya

I'm just looking for some advice

I am recently a single mum to a 19 month old little boy.
I am currently not working ( as I moved back to England from Scotland to be with DS dad) and I'm on universal credit ( for now)
I applied for a uni/college course to refresh/add to what I'm already qualified to do which is Special effects. The duration is one year. Then I'm hoping to be self employed.
I've recently been accepted on this course which starts in September.
By the my DS will be 2years old and I will be driving (test soon) .
I'm aware he can get 15 hours free. (30 hours if working)
What I'm wanting to know is will this course effect my Universal credit, what about funding if not job/Universal credit and can I get childcare somehow while I study?

I'm just a little confused with it all.
I don't want it to affect my rent or money ect but I really want to add to my qualifications and set up self employed.

Advice /experience /information would be much appreciated.

Thanks DollFace13
