I hold the belief that education should be accessible at minimal cost and have compiled a vast collection of free resources and materials found online. I have created this webpage to keep track of and share this information. There is a diverse range of content available here as a starting point. If you cannot find what you are looking for, kindly bookmark this page and check back regularly as I intend to add more resources over time.
Please note that I have no affiliation with any of the listed resources, trainings, webinars, courses, or other content. Kindly inform me via email if any of the links are broken or of any other issues. I have not personally reviewed all of the material and cannot guarantee that everything is up-to-date, accurate, or of high quality. If you have any questions or concerns, feel free to let me know.
