Ah crap I printed out an iTute exam, panicked as I couldn't even answer the first question...
Do TSSM and TSFX go beyond the course?
TSFX exams contain a lot irrelevant material - I encountered some questions in a Methods TSFX exam that wasn't even on the Spec (let alone methods) course - it's not that it was difficult, it was just plainly extraneous (i.e. having to sketch and solve equations containing hyperbolic functions like cosh and sinh). Unless you have no exams left to do, I wouldn't recommend attempting their exams. The study notes are decent though.
TSSM is challenging at Spec level, but I found it great for methods with a desirable difficulty level.
btw, some companies (neap, iartv, itute) purposely make the exams harder, so don't become daunted if you're finding it difficult. Chances are that everyone else is too
