Answer: Summer School
Explanation: I don't know if you expected this answer but you can always go to summer school and learn something that you want to know or ask someone for options in subjects to learn in summer school. Gives you more "advanced" education when school goes out for summer.
"A summer school is a form of education provided by universities and international colleges during the summer vacation, with courses usually lasting one to eight weeks. Students engage in full-time intensive classes related to a chosen subject and have the option to attend extracurricular activities designed to encourage socialization and stimulate cultural awareness. Summer schools offer courses that may aid students in revising a subject studied during the previous academic year, further exploring a known subject, or discovering a new interest."
I found this on the internet to help me explain what I'm trying to say
