学生对 加州大学尔湾分校 提供的 Perfect Tenses and Modals 的评价和反馈

I loved this course. I am pretty good at grammar, but it was good to review some rules. I took it in four days, each day I completed one week. Every day I spent on average two hours on the course.

That is a well done, informative course. I brushed up my English and understood some basic — and yet overlooked— grammar rules and the logic behind the use of the present perfect tense.
