You can apply to change your status from B1/B2 to F1 by filing Form I-539 with USCIS before your current status expires.

You cannot begin studying until your change of status is approved — this process may take several months.

If you entered the U.S. on a B1/B2 visa with the intent to study, it could lead to denial due to visa fraud concerns.

In many cases, it’s faster and more straightforward to return to your country and apply for an F1 visa through consular processing.
