Final answer:
To register for the PSAT online, you typically need to go through your high school, which can provide instructions and a code for registration on the College Board website.
The PSAT is offered annually, and deadlines for registration are usually a few months ahead of the October test date.
Step-by-step explanation:
The easiest way to register for the PSAT online is by visiting the College Board's official website. Typically, registration for the PSAT is handled through your high school, so the first step should be to check with your school's guidance counselor for the specific process your school uses.
If your school has enabled online registration, they will provide you with the necessary instructions and a specific code to register. However, you cannot register for the PSAT directly as an individual; it must be done through a high school or educational institution.
The PSAT/NMSQT is offered nationally every year in October, and schools select a primary test day with an alternate day available.
Be sure to register ahead of the deadlines, usually a couple of months prior to the test date, to ensure a spot. Also, there may be a fee to take the PSAT/NMSQT, unless it is covered by your school or a fee waiver is applied.
