I'm gonna be completely honest here, and I will say that I'd rather sit one of these exams rather than an Exam 2
Like seriously, Multiple Choice annoys me (it's like they work out the answer choices to trap you!)
And the Extended Response in Spesh are wordier than here
This is much more like "real maths" - i.e. Exam 1 stuff
In my opinion though, they seem to do more involved calculus, but less kinematics, dynamics and the like
They don't seem to have stuff such as Inverse Trig functions, and Reciprocal Trig functions...etc
It's like saying take the Calculus and Complex Numbers chapters and also a bit of Mechanics from Spesh, blow it up and add more content and you have this - I personally think Specialist Maths is way too wide, it tries to cover too much :S
