Well you guys would be jumping up and down, and screaming at the top of your lungs if you were me. This is because I didn't need to go to the TSFX lectures to learn from MR Mac or what you call him Ian McDonnell.
I HAD HIM AS MY TEACHER FOR BIOLOGY FOR THE WHOLE YEAR LAST YEAR(2012)!!!
He's a very good teacher, does basically everything in class as he would at the lectures, even more!
Take this as a pinch of salt, but even though I had mr Mac as my bio teacher, I did barely any holiday homework thinking that mr Mac could teach me it all. oOOoOH was I very wrong. Teachers can help you oh so much. Without doing holiday homework but having a great teacher can't make you the best student you can be. It is up to you to do the work and stay in front to get the best scores you can.
So the moral of the story, no matter who your teacher is you must have a sound understanding of at least the first few chapters so that you will not fall behind like me and get only an above average score.
Just my 2 cents
