Tssm or Tsfx for exam rev?

[MrsStark]

Hi all,
Has anyone been to  either of the lectures from these companies?
I'm doing year 12 bio and wanted to attend one but I don't know which one is most beneficial. I attended Tssm winter school and found it pretty good but there are some people that say that tsfx is the best?
Should I try out tsfx or stick to tssm?
Whats your experience?

I attended the TSFX Biology revision lecture. It was really good. The notes are GOLD. However the only negative is that it goes for like 9.00 to 5.00 which is pretty draining..but others wise, its really good. Most lecturers are nice and engaging except I had one who just told us to highlight the notes through out the lecture..
