Schoolhouse.world offers certifications in a variety of categories, including math subjects, science subjects, and some specific test prep categories. For most math certifications, you have to record yourself solving problems on Khan Academy. In these cases, personal computers, including laptops and desktops, work best for completing certifications. Devices such as iPads and tablets are incompatible with our system for recording the certification videos. Google Chrome is our only officially-supported browser for recording certifications, so please use Chrome to record your certifications.
