Should I take the sat without studying

So I am taking sat without studying to see where I am currently and then I will take it 2nd time with studying. Do you think this a good idea or no? Can I hide scores from colleges cuz Yale sees every score.

The College Board does offer a “Score Choice” feature, that lets you choose which scores to send. However, in the FAQ on that page, it indicates that

Colleges cannot opt out of or reject Score Choice. Score Choice is a feature available to students. However, some colleges require students to submit all SAT scores. Be sure to check college websites to learn more about their score send policies.

It may be that some of the schools you are applying to require that all scores be sent. As a result, you may not want to take the SAT without studying if any of the schools you are applying to require that all scores be sent.
