The most popular extra (额外的) classes at my school were piano lessons and drama club.Both classes offered exams students could take.
这里的could Both classes offered exams students could take
The most popular extra (额外的) classes at my school were piano lessons and drama club.Both classes offered exams students could take.这里的could Both classes offered exams students could take
could 是can 的过去式
Both classes offered exams students could take =>Students could take exams that two classes offered
学生能参加这两门课提供的考试
全句都是过去时，所以could 就是 can的过去时
Both classes offered exams students could take
即 两门课都有可让学生参加的考试。
这里的could可以当可以或者能够讲，Both classes offered exams students could take 都能够参加两个课程所提供的考试。
希望我的回答对你有帮助，祝好。不明白的再问哦。
