Digital Tech Notes (JSS1 - SS3)

About Us

About Digital Tech Note

Welcome to Digital Tech Note — Nigeria's Free, Curriculum-Aligned Computer Studies Resource for JSS 1 to SSS 3.

Digital Tech Note was founded to solve a problem every Nigerian secondary school student knows too well: Computer Studies and Digital Technology notes that are either too expensive, too vague, or simply not aligned with what WAEC, NECO, and JAMB actually test.

This platform exists to change that — completely free, always up to date, and written specifically for the Nigerian classroom.


Who Is Behind Digital Tech Note?



My name is Echofu George Adah — known to students and colleagues as Sir George.

I hold a Bachelor of Science (BSc.) in Computer Science, a Postgraduate Diploma in Education (PGDE), and I am a Microsoft Certified Azure Database Administrator. I work professionally as an ICT and Digital Technology teacher and Network Administrator, with hands-on experience delivering Computer Studies instruction to junior and senior secondary school students across Nigeria.

Beyond the classroom, I am the Founder and Chief Executive Officer of GeoWeb Technologies Limited, a Nigerian information technology company committed to delivering cutting-edge ICT solutions. Digital Tech Note is the educational arm of that broader mission — bringing the same professional-grade ICT knowledge into secondary school learning in a language every Nigerian student can understand.

I built this platform because I understand both sides of the desk. As a trained educator with a PGDE, I know how to break down complex technical concepts. As a working IT professional and Microsoft-certified database administrator, I know which of those concepts actually matter in the real world. That combination is what makes Digital Tech Note different from a generic blog.
