I was working for 3 years as a programmer in a company when one day i decided to leave that job. I didn’t have any savings, nor was I ready to start searching for a new job, so I spent 4 months studying for the exam and got it. I got a new job 2 weeks after the exam. The salary is almost twice as high as my former employer offered me.

I passed the exam with a great score. I was very nervous going into the exam because it was my first attempt at earning the credential. I found the sample questions in your Study Guide to be more realistic than what I experienced on exam day. Your study guide helped me to identify gaps in my knowledge and provided detailed explanations that allowed me to answer the questions correctly on exam day. Thank you for helping me pass the exam!
