The first two modules of the lectures were very easy, introducing basic concepts of chemistry and physics, something that you study in 7-8 th grades at school. But the biology lectures were too full of content, my friends from ABCT told me that the content included almost everything that they have studied for the last two-three years in their high school, therefore it was very difficult to remember all the content for those with no experience in biology (including me). The food science module was pretty interesting though. Overall I feel like the difficulty level of different modules should be more uniform
