[eliff]

Hello,

Could you please check the sentence whether they are correct?

Normally we use 'could have/might/would have' have in past.But Today I was surprised when hearing this.

a) If I had gone to school, I would have found a jon now.

b) You could have done my homework now.But I didn't.

Thanks

This is fine, and "could have found" would also be fine.

b) You could have done my homework now.But I didn't.
This doesn't make any sense if the whole thing is said by the same person.

Thanks

Why were you surprised to hear the first one?

Thank you first.I thought that we had to use 'could have/might/would have' have' with the past adverb of time.But I think that 'now' shows the term from past to now.

Is that right?

For example :You could have done my homework now.But you didn't.

You can't use "now" with this sentence. You can use "by now".
This also needs fixing:
a) If I had gone to school, I would have found a job by now.
"By now" does refer to the past.

a) If I had gone to school, I would have found a job by now.
"By now" does refer to the past.

Though it's a past that extends up to the present moment.
