First of all, thank you so much for creating this wonderful study guide to the texes test. It was a great tool and one that helped me finally pass my EC-4 exam. In using your product I had a 28 Point increase in my test score which helped me pass the test. I would tell anyone who is having trouble passing the exam or in future will be taking the exam to purchase your product. I wished I would have spent the money the first time I took the test. Thanks again!!
