Review by Melissa Aybar
It was very interesting / however (unless I am wrong or my computer is faulty )there are mistakes in some of the quiz results that share similar answers, also the definition of an ellipse cannot be the same as for the hyperbola (also found in the quiz results). Apart from that the teacher is excellent & very capable but his graphic capability are not up to scratch (a CAD program would help)
