My experience in participating in Quick books classes were very positive. My instructor Bob was right on point. His efficiency as well as his patience and kindness allowed me to complete this course with the knowledge and understanding that I will need to be successful in my business ventures. I also feel that CTS is an educational entity that is doing well and should be acknowledged as a positive force in achieving its goals of preparing its students to be vital in today's technically charged society.

I found the class very informative. I learned a lot. I only had two problems. One, I got the digital book so I was unable to refer back as he was talking about what page we were one. The second was the sound kept cutting out. I was the only person having this problem so I'm assuming it was my computer.

I just want to express my deepest gratitude for the opportunity to be a part of the CTS QuickBooks class. Walking into this course, I wasn’t sure what to expect—I just knew I needed help, direction, and a better understanding of how to manage my financial future and to obtain employment. What I received was so much more. From the very beginning, the instructors were patient, knowledgeable, and incredibly supportive. They didn’t just teach QuickBooks; they created a space where I felt seen, encouraged, and capable. Every lesson built my confidence, and every moment in class reminded me that growth is always possible—no matter where you're starting from. This class has not only given me practical skills I can use right away, but it has also given me hope. Hope that I can run my business better, be more organized, and take control of my finances in ways I never thought I could. Thank you, CTS, for investing in people like me. Your impact goes far beyond the classroom. I’m leaving this experience feeling empowered, inspired, and ready for what’s next—with humility in my heart and gratitude on my mind. — With sincere appreciation, Dawn

The instructors are very clear and specific. The overall environment is very friendly and that makes it easier to ask questions or to not feel to worried when I make a mistake because they just help me to understand and catch up.

I’ve been doing these courses since December this company has done nothing but helped me learn. I have ADHD so things don’t stick but the teachers make sure I understand everything. If you are hands on they will make sure you understand everything they teach . The professors do walk you step by step through it all so you will be prepared or test and certifications.

I give CTS five stars for the QuickBooks online class that I took recently. I did this because I have took in the class twice. The first time was enough although there's constant updates with QuickBooks and CTS and their instructors are very up-to-date on QuickBooks information very educational I highly recommend. This is good for beginners and for people trying to obtain a touch up in QuickBooks online. The class is very straightforward and to the point.
