Well with TSFX for unit three, the first lecturer named Kelly (macrob girls teacher??) was fantastic.
She went through the whole first booklet on AOS1, told us what important points to highlight, and presumed learning from Units 1&2 and a few tricky exam questions. This was very beneficial leading up to exams.
Ian then took the lecture for AOS2-detecting and responding. He only got through half the material of AOS2, and barely touched on the immune system. Don’t get me wrong, he is a great talker and would make a fantastic class teacher. . . .
But as for a lecturer, he spent too much time showing us pictures, vids, and facts not relevant to the exam. From a lecture you need someone who is speedy and detailed, Ian didn’t cut it.
