What to use?

I just realised that this is something people might want to learn but don't know where to start

So here! I'll pass on everything I've learned at school & college. This can help if you're doing it as a hobby or if you're struggling at school with Comp Sci. I'm in Scotland, so I'm doing National 5 Computer Science right now, but will be starting higher soon. If you're English, I'm pretty sure that's the equivilant of GCSE computer science, or slightly more complex. I'll be starting at the basics and slowly getting into slightly more complicated stuff.
