I played my firsty like well, not good. Until I learned the terms and policies. Lol. Then over time I did get better though. I think that you could play your first year as a confident witch/wizard in training. I mean, if he/she is a pure blood or at least a half blood, I think he/she would be more confident. Or if he/she was a book smart muggle born like Hermione, then they would also be confident. Unless they are half bloods like Harry or Tom...who grew up in the muggle world, then they would be less confident. Then again, Tom I think would probably already be confident, too confident for his own good because he already had some what of a handle on his magic.
