Hello, I've used WingClass.com, here is a little bit of my suggestion, I hope it can help you:

The webpage layout and style are good, suitable for students to do their study;

There are diversified functions, such as exams, trainings, oral tutoring, classmates' circle and so on, and I like one of the exercises very much, it's a classic movie dubbing.

There is a personal learning profile, which contains completed assignments, average time spent, grade trends, etc. for students' easy reference.

But one thing that is lacking in Wingschool.com is its VIP system. The shortest time is one year at 365 dollars. Although it is voluntary, there are many limitations to this system. If you don't open VIP, you can't know the grade of each assignment, you can only do the exercises in the lowest class mode, you can't even re-answer the questions, and you are restricted very much.

We are now required by the school to use wingcourse.com, so I didn't return my number, but don't really recommend this learning site. What I would recommend more is Homework Together, which I have used before. It has more varied exercises and is even more student-friendly than WingClass.com, incorporating game elements and unlimited rights.

The above is only a personal opinion, I hope to be able to bring help to the owner.
