I like the whole 'this is not your first lesson' thing but I suppose there's the option of saying it is if the professor wants to I definitely am glad that my first actual lessons with staff charries I RPd them as their first lesson taught at Hogwarts since IC wise it made it a lot more interesting and fun for people to adjust to the individual charrie teaching and points 'distribution' ahem style. I don't miss the old 'what do you know about X' stuff but I also remember as a newbie how fun it was to literally experience that first time too so there's that lol.
