The idea of Quizeey, pool of quizzes, first came out when I was studying for the AWS Certified Developer - Associate exam. Most of the time I used my smart phone to study the AWS practice questions which was a PDF file. It was so hard to see the PDF file through a small phone screen and with an answer placed right under the questions make it hard to concentrate. So I decided to make a mobile friendly pool of quizzes to study more effectively.
