No antenatal classes!!

I'm from the UK, and am currently living abroad. I will be moving back to the UK at 35 weeks! (Great timing, I know!!) 
​Where I am currently living there are no antenatal classes at all. So I was after some information about what you would normally find out in these? I feel very unprepared because of this, even though it's early days for me still...I'm a planner, and want to be as prepared as I can be! 
​Thank you in advance! :)
