“I passed the PE on my first try. I did the DTC course as well as a couple other prep exams. Those tests were ok for continued practice, but the DTC program was 99% of what mattered to my preparation. I would have been fine with just DTC. Dr. Tom’s program was exceptional considering the breadth of topics that were possible, his videos were excellent and the print outs are well organized. I recommend DTC to anyone who wants to get a PE. Thank you!”
