Reviews

I learned a lot. Thank you. I liked that we had one program that was developed more and more as the class went on. That helped me to see how the new concepts were being applied, and it was exciting to watch the program become more advanced. - Courtney G.

This course was well written and did a great job organizing each topic. The learning material was concise and to the point on what we needed to focus on to learn each topic. The exercises provided were very helpful, and I liked how the main payroll exercise built upon itself through each topic, so you can see specifically how each topic could change the program and what you would use it for. - Robert P.
