Affiliate Marketing Secrets

I am 14 years old. Me and a friend are very interested in stocks. We want to spend some years researching the ins and outs of investing, and then start investing maybe when we are 15 in a few months or 16. I realize that our legal guardians are supposed to open a custodian account for us. Where would I go to open this? Also, could someone just explain some simple things to me very very briefly, like NASDAQ and DOW? Im reading a bunch of books, and I would just like to increase my vocab. Thanks!

I started school in California (United States) during the 1950’s, a time that was defined by the second Red Scare (communism) and the McCarthy Era. Each semester my school district required the students to give a document to their parents or legal guardians to complete and sign. The documents stated in part that the parents or legal guardians of the students are not members of, or affiliated with any organization that sought to overthrow the legal government of the United States. In 1960 my school district discontinued the practice of requiring the students’ parents or legal guardians to sign the document.
What type of documents (if any) did your school district required?
