I really wish there were more past papers for this. Unlike the AS level modules there doesn't seem to be any legacy modules that correspond to it. Like with mechanics last year the papers they had before were virtually the same stuff but this is different.
All the past papers I've done have been all over the place. I've had a B, a D and an A (in that order!) in the 3 papers I've done so far. The grade I'll get will really depend on exactly what comes up and how harsh the boundaries are >_<
