It probably doesn't meet your definition, but if you were a K-12 student you could:
* Homeschool
* Use your local school's curriculum or a public one like Common Core or another one of your choosing
* Use one of many amazing online sources, like Khan. The great thing is if you struggle, you can always find an alternative teacher. I've found sometimes I need multiple different explanations over the course of weeks to understand a topic.
* Many communities in larger towns & cities have tons of offline learning opportunities for groups.
