My first course was 4 hours, I did it in a few days, "nugget-style". The instructions are very clear and easy to understand. There is even a hint to help you get the answer. I love the learning style that is used, it engages me.

I have gained a lot of practical and logical thinking skills, along with patience for myself and confidence in myself that I can learn programming. Years ago, I would have never thought that I could learn programming in any way, shape or form, and I was able to obtain these certifications and skills with Codefinity.
