I'm in history HL in a very small class with a very under-qualified teacher, and if I'm honest, I don't trust his judgement on my IA topic. The topic I proposed was: "To what extent did the Battle of Stalingrad force Hitler out of Russia?". I've also been considering similar topics such as "How impactful was the outcome of the Battle of Stalingrad on Germany?" I am really interested in this topic (and the Wehrmacht's time in the USSR in general) but I don't know if this is too specific, not specific enough, overdone, or even viable as an IA topic. He sort of just said "yeah okay" without giving any criticism or really any comments with substance. Would really like some feedback ASAP, thanks!
