I like the idea of building your circuit in simulation first, even to get the basics figured out, saves burning out IC's or other components. More so when learning new things as you can test them out without having to get out the soldering iron.
Regarding the PC I didn't know it wouldn't work inside school hours so 30mins before I went to RS I tried to print. I haven't touched it since as it said if I went on the 30 day trial I would have access all day, so I clicked and my 30 days are up. Ill have a look for the version you speak of thank you.
