Dual Track Learning

Why choose between job skills and a cert? We build you a custom study schedule in your dashboard that runs a ProCourse and your cert prep side by side, around the days you can study.

Break In or Level Up

Breaking in? Build the skills and study for an entry cert like A+ or AZ-900. Leveling up? Go deeper with advanced tools and certs like CySA+ or CISSP. Either way, you get hands-on with real industry tools.

Fully Interactive Courses

The traditional one-size-fits-all education system doesn't work for everyone. Many can't just sit on their hands and learn. Our courses engage the student every step of the way.

Before you start

None. Our courses and preps assume you know nothing. Each ProCourse starts with Linux fundamentals, which is essentially teaching you how to use a computer, but through the command line.
Just your phone or a computer. Our courses and preps are 100% mobile friendly and will work on your phone just as well as on a laptop, so you can learn anywhere you can get a signal.
It's a plus, but it's not required. About half of IT support specialists and systems administrators in the US don't have a bachelor's degree, according to the Bureau of Labor Statistics. That includes our founder, who's a working Systems Engineer.
Here at opnF.sh, we'll build you a custom schedule with a calendar right in your user dashboard, in a time frame that fits your goals and availability. Typically, though, a ProCourse takes about 2 months. Paired with CertPrep+, you're looking at 3 months.
Not only can you try, but you can gain a significant amount of knowledge with a free account. You can learn to speak the language of the computers that power the web, as well as prep for entry-level certs.
A subscription gets you access to all content across ProCourses and CertPrep+ for a monthly or annual fee. Buying lets you purchase a single ProCourse to own forever.
Yes. opnF.sh supports organization accounts, allowing leaders and teachers to track their students' or employees' progress, as well as assign material.
30-day money-back guarantee on everything. No questions asked. If you're not satisfied, email us and we'll refund you in full. 5% of every purchase is donated to the Boys & Girls Clubs of America.
