Is it a must to provide school documents on interview date in the f2a category

It is best take all documentation that may be requested to the interview. This will avoid delays in the adjudication of your application. Whether the records are likely to be needed would depend upon more information about the case and the interview. For example, are you seeking adjustment of status in the United States? If so, the records will likely be relevant to determining if you maintained lawful nonimmigrant status. You can read more about family immigration at http://myattorneyusa.com/family-immigration.
