Welcome to the forum mate, plenty of sound info on here and great people.
Guessing you're 16/17 then? Best of luck with it, get on the phys early but don't start too hard, build up gradually
Just some basic forum courtesy, I noticed you're commenting on a lot of old threads from back in 2015/16 etc that have pretty much been answered which brings them back up in the recent threads section etc! (this is called bumping)
It's generally not the done thing unless you're providing a really sound answer that hasn't been put on there or have a question that hasnt already been answered on the forum
