The course isn’t rigorous. I think your positive experience was not shared by most students. From my experience and after talking with people who also took the course, many of our classmates were struggling with the content. So much that the teachers gave away the solutions before the assignments were due. The certificate you got at the end of the summer was a certificate for merely completing the assignments. So you could pass the program by copying down the solutions from the teachers. I acknowledge that Mr. Alex and Mr. Aleks tried their best to teach us but this tells me:
1 – The quality of the program isn’t very good or,
2 – They are admitting too many unqualified students to increase revenue, and the program is not very prestigious and exclusive as they say.
