Hi, I'd like to ask an Austrian friend who was giving a lecture (in English) for some clarification with RE: some notes I took during the lecture. I don't want to imply that they did not teach the topic clearly - I'm pretty sure the slight confusion over what I have written down is due to my writing fast/ a lot of subject being covered and not because they were teaching in English (i.e. I don't want them to think that their English isn't great, because it is very good). So to ask politely "It's possible that I misunderstood something you said; can you please clarify this for me?" - is this correct: Ich denke (or "es ist möglich"?), daß ich etwas missverstanden haben könnte, dass Du sagtest (was Du hast gesagt?). Könntest Du klären Sie bitte das für mich? If there's a better way to say this, please feel free to modify! (I'm not very good at past tenses yet.. what I wrote is probably all kinds of wrong!) Vielen Dank!
