I’m not familiar with Shaw Academy so no opinion about them. Alison has been around for years. I’ve found them just so-so depending on what I’m trying to learn. The last time I used Alison, it was free and you get what you pay for in most instances. Most of the decent, accredited educational platforms are going to charge you for their services. There are some online high school and college platforms but I don’t remember the names right this second. So keep researching until you find what you’re looking for. Whatever you do, even when losing hope, never stop looking for what you need. It’s out there waiting on you to find it Also, you didn’t give us much info on what you’re trying to learn so we could throw out many names of platforms for you and none would be what you need
