I like that it has many options to choose from in order for you to find out what will benefit your students best! It's easy enough so anyone can use this software but if they have no experience with an online platform then there may be some things which are difficult or confusing about using KCLM S as well because of its ease-of-use nature (I think). We're able just go into our own content right away without having any teacher training first - great feature!! Nothing really at all since we've been working through implementing different aspects such as quizzes/tests etc., surveys / feedbacks & student information cards within one area called "Student Information".
