Hi friends, am I using the tense correctly? 1. There are a lot of things that I wish my high school teacher had taught me. 2. There are a lot of things that I wish I had learned in high school.

Charlie gave an excellent answer.

Kai, In my Canadian opinion - most times we'd use your example - after wish we use the would construction. Example I wish I would have known. I wish I would have traveled before attending university. (also, because English speakers can be lazy, I might omit "that" in either sentence)

To me, both sound pretty natural in speech. Probably because Kai's structure is fine with 'could'. A: I wish I could have gone on the trip. I was too busy. B: I wish I would have gone on the trip. I wasn't busy - just stupid.

It seems first right
