Free, Foundational Self-Paced Computer Practice Labs
Tech Learning Collective provides numerous free, self-paced practice labs that you can use to jump-start your learning before you ever join us at one of our events.
These labs are provided free of charge, and are always available, so feel free to take as long as you need to work through them. Our “Foundations” series of courses are designed to introduce you to the most important foundations of our material. We also offer several bite-sized modules of additional sample learning modules to show you some of what our longer in-person and online webinar workshops are like.
Of course, nothing can compare to learning directly from a teacher whom you can actually see and ask questions of in real time, but we hope that these self-paced learning modules will whet your appetite until your next (or first) class with us!
