Cengage learning is not that much bad I thought but the videos are not of good quality and the sound quality also bad in those videos that there are good content and they have brought a very good products in the books and exhibit I think that’s great and the website need worth more upgrade so that we can excess everything fast and the Teachers should give some works in the book content that are wrong what’s needed in the book the mistakes they should also be viewed in the website so that we don’t have to fall in any sort of problem altogether I love it
