I finished in 2010, and i had heard about these lectures.
i did go to:
english - as you like it
english - bladerunner/frankenstein
legal - workplace
mastering the exams
i believe that the notes are worth the money alone, even if you dont pay attention in the lectures go for the notes (or get them off your friend)
my friend went to the other legal lecture for our other elective, and we both got the notes for crime and law and society off a girl in the year above us. they were actually amazing
as for the english ones, i think they were helpful.. not as helpful as legal but good. as you like it was terrible as there were a lot of standard kids in the lecture who didnt even know what the text was about (i went to the ones just before the trials..)
mastering the exams i didnt find that useful, but as it was free it was helpful..
i heard that their maths ones arent very good, but i dont know from experience
the alpha omega education FREE maths ones were so good (i went in the summer holidays last year) and i ended up enrolling i was so amazed.
yerr thats just my experience :\
at the end of the day.. you cant really put a price on your education and its still way chepaer than private school education?
