Unfortunately, many aspiring tech professionals, especially students and recent graduates, often give up on this dream because of the high cost of enrolling in tech training programs. If you’ve ever tried to register for a coding bootcamp or a digital marketing course, you know what we mean, many of them start from ₦150,000 to ₦500,000 or more.
I remember my own struggle vividly: In 2019, fresh out of the polytechnic, I wanted to learn web development. After days of searching online, I found a training center in Lagos. The course fee? A whopping ₦350,000. It was simply out of reach.
But here’s the truth: you don’t need to pay a fortune to learn life changing tech skills. In fact, many of the world’s best tech talents today started with free online platforms, building their knowledge, portfolios, and confidence from scratch.
So today, I’m sharing 7 trusted, free (or nearly free) platforms where you can learn valuable tech skills, gain real-world knowledge, and kickstart a career that pays for life.
