You can choose what classes you want to do and how you want to do them. There is no set schedule saying (for example) you have to do U.S. history, biology, and algebra all in your freshman year. You can wiggle around to where the workload and learning is best for you.
SRO lets us students pick all of our own classes with help and guidance from a Mentor and 4-year plan. We are given the choice to choose what courses we want to use, and how often we want our deadlines, then have to be self-motivated enough to keep it. We always have teachers (our Mentor especially) to help us with any questions we have, and are promised a quick answer, being encouraged for us to do the same if a teacher asks us anything. We have plenty of super helpful resources, but a lot of our learning and getting stuff done is up to us. Unlike a public school, we are given the work and told we can do it in whatever order we want, as long as we get a certain completion percentage done to show that we're using the money and tools provided as we should. This system has been super helpful for me when I have long periods where I cannot work due to physical problems and appointments, or even just a writer's/learner's block. It also allows some of us to be able to take vacations in the middle of the school year to relax and destress for a little bit before getting back to work without having mountains of things to do when we get back. This school has saved me from so much stress I would've had otherwise had I stayed at my previous in-person school.
