I like that it is very easy to use, no prior experience required! It's great for self-directed learners who want more flexibility in how they learn compared with traditional classrooms or courses where you're told what topics need attention first before moving onto other things (i know this sounds strange).
The best thing about engrips are their videos which help explain concepts clearly without any distractions from text/lectures etc., so there isn't much we dislike as such but if anything can be improved maybe would include some sample projects at times? This could really improve engagement levels of students because when someone has an idea then all he needs now is guidance towards implementing his ideas rather than having nothing tangible available to guide him through implementation process - something else i have experienced while attending universities across Europe during my studies years ago.
