I didn't have the time to explore tons of other study options for the L&E exam, so I just used TDC; and I passed! As I progressed through the course, I could feel my confidence build. By the end, I felt well-prepared. Actually, I found the TDC practice questions more challenging than the ones actually on the exam! I'm so grateful to TDC and will definitely use it for my other exams. Thank you TDC!
