While I (was walking) across the campus the other day, I (met) my old friend Bill, whom I (HADN'T seen) since May. Naturally, we (stopped) (to talk) to each other for a few minutes. I asked him how he (was doing\did) in his classes that semester. He told me that he (had taken) a course in English that semester. He said that he (had completed) the elementary course two semesters before, and by the next semester he (would be ready\would have been) ready (to take) the most difficult English course offered at this school. He also said that he (was) interested in getting his degree as soon as possible and he (had already asked) his adviser for permission to take the final examination. "I am glad (to hear) that you (have made\are making) such good progress", I (said) to Bill. Then I asked him if he (could) tell me the secret of his success. He answered that the secret of his success (was) simple and he (studied\was studying) at least two hours a day to improve his English.
After that I told Bill I (was having\had) a little difficulty with my course in French at the moment I said that i (hadn't studied) very hard the last semester, but I (would work) harder in the future.

примерно так, но думаю 2-3 ошибки присутствуют по объективным причинам. Язык - дело субъективное, часто постановка времен зависит от личного восприятия, а учителя зачастую проверяют просто по ответам, не задумываясь над вариантами в отличие от студента, который рассматривает все варианты. Сама учитель ))
