I finally took the time to study all the material just as this program recommends and focused all my energy and found that when it was time to take the test, I felt confident! I recently lost my father to cancer and I felt very discouraged when I didn't pass the test last year, but I can proudly say that the TDC material is excellent and better than other study programs out there. Thank you for encouraging me during my hardship and throughout this journey and continuing to help me succeed. On to the next test!
