I'm not sure how to use tenses in some sentences.
A: Have you ever come to one of these seminars?
B: No, but I went to a similar seminar in Europe last year.
A: Have you learnt / Did you learn a lot at that seminar?
B: Not really, but I met/have met many interesting people during that week in November.
I an unsure whether I should use "Have you learnt" or "Did you learn”.
Is it okay if I use "Have you learnt"? I think he might learn something from the seminar which has an effect on the present moment.
And should I choose "met" or "have met"? Is it possible to use "have met" since there is "during" in the sentence?
