4Tests.com was started by two recent college graduates, who while preparing for their Microsoft Certifications realized that there was minimal to no resources available on the internet. This inspired them to begin researching what areas of opportunity were still available on the web, and 4Tests.com was born.
Now 4Tests has grown to provide millions of users assistance in preparing for their upcoming exam.
