【實用教育app】Edexcel C2|最夯免費app

If you’ve seen ExamSolutions.net desktop version but want the ease of use on your Android Mobile or Tablet without the adverts but with all the video tutorials then this app is for you or your school.

Each app in this series covers the essential topics for the module, presenting them in short video tutorials and explained in a clear mathematical style so as you can progress quickly and smoothly through the topics. There are further supplementary exercises and worked solutions from past papers for you to try, essential to improving your grade.

It is like having your own personal tutor but at a fraction of the cost. You can pause, rewind, play again and again and learn at your own pace. Learn on the go or place a video in your favourites to view later.

This is a valuable resource that will work side by side with a textbook and should help you to get the grade you want, whether you are at school, college or just studying on your own.
