CPTS taking forever

I started working on the CPTS at the beginning of November and was stuck on the PtT Module for the last three days. It's frustrating beyond any explanation to see how slowly the whole process goes. I've a well rounded technical background, took the TCM courses beforehand and was utterly convinced, I could pass the CPTS in a couple of months. Here we are, running headfirst for the 3 month mark and I'm only 1/3 done with the material. I'll still need to go over everything a second time and practice so there's so much more to do that I'm starting to wonder, if it's even remotely realistic to pass in the next 3 months. The day estimate for the course was around 48(?) days or so. I'm well beyond that and I'm stating to feel really stupid.
