I like that this program allows you to learn at your own pace, so it's not overwhelming with too much information or exercises for one person. It also helps me get my work done faster because everything is organized into sections, which makes managing time easier than using other programs! There isn't really anything bad about this product; however, if there were improvements made then maybe they could increase functionality? For example, when creating an account, sometimes it can be difficult to find where certain functions are located within the application. This doesn’t seem very serious but just something we ran across while trying to figure out how things worked. We use pack back as part of our daily routine before going home from school/work. It keeps us up on what homework assignments need to have completed by next class period, etc.
