final assignment in 4 reviews

Also, final assignment is confusing: while it declares to create some description of real working system, it's goal is "just write down every technical term you heard".It's a formal course, not about learning, just memorizing some tech terms.

The final assignment had two glaring errors in the marking rubric, so overall good content but the text needs attention to detail.

This is a great class, and I learned a lot.However, the final assignment is not very fair.

Description for the final assignment was too vague.
