That's great. You can really start learning after this "phase". The point is now that you can check "yes" on applications as being a high school graduate. It's not your fault it did not make sense. It Does Not make sense how they conduct K-12 education in most government run schools. They (as an institution) don't care how we feel for the most part. So now, just decide on future education goals and go for it! You'll be fine! : ))/
