Yes, you can change your B1/B2 visa to F1- student visa. Your request to change status must be received by CIS well before the expiry of the date on your I-94. There are other issues that you must consider before you apply for the change to F1 visa. They include but are not limited to the timing of your request to change status relative to when you entered and your representations when you entered as a B tourist; you must also present solid evidence of your financial ability to pursue the course of study without resort to unlawful employment or becoming a public charge. I urge you to hire an attorney for this matter.
