Hello, teachers.<br/><br/>I have a question about tense.<br/>Which of the following two sentences is grammatically correct?<br/><br/>#1 Didn't you learn more when things did not go well than when everything ran smoothly?<br/><br/>#2 Haven't you learned more when things did not go well than when everything ran smoothly?<br/><br/>To be more specific, I wonder if you can use "Haven't you learned" in the sentence.<br/><br/>Thank you very much.
