This interactive map shows places you can volunteer at! Click on the red pins for more information on volunteer locations. The green pins show places we suggest as community center hubs of innovation and learning. They can help you, as students and mentees, with school or to learn a new skill. They can also provide in-person mentoring.
The local library is an amazing resource. They provide computers and printers (small fee), as well as some free tutoring services. My brother took a free practice SAT test at the Burlingame library! In terms of online help, you can't go wrong with Khan Academy--they provide free SAT prep, and we still use it for college courses.
