Hi
I found Cambridge Books 1-7 online and i was wondering is it useful to practice all the books or should i just practice with the latest versions?
Because it looks like that format has been changed a lot since old ones and i am not sure should i consult old books or not?? ???
Please advice, if somebody knows anything about it.
Thanks!!!
