About the Summer Accelerator
Gravitas offers intensive summer courses to aspirational students in all grade levels. Join master teachers and peers from the around the world for 80 minutes of engaging live class discussion and complete the rest of your work asynchronously as you leap ahead in fields like math, science, and computer science, take interesting elective courses in philosophy, ethics, and English, and ignite your passions in our summer Passion Academy courses.

Why Take a Summer Accelerator Course?
The main reasons students take a summer accelerator course are:

• Go further faster in a given field, typically math or science. Taking more rigorous courses in these fields significantly boosts students' chances of gaining acceptance to selective universities and program.
• Free up scheduling space for more elective courses during the school year
• Jumpstart their college application completion process
• Bolster their college applications. Over the past five years, students who took a Gravitas Summer Accelerator course later matriculated to CalTech, Cornell, Dartmouth, Johns Hopkins, MIT, Northwestern, Notre Dame, Princeton, Rice, Stanford, UChicago, UPenn, and Vanderbilt.

Character Formation Program Included
All students enrolled in a Summer Accelerator will also take part in the Gravitas signature Character Formation Program so they can continue to grow in wisdom, faith, and virtue throughout the summer.

Prerequisites
Prerequisite courses and grades are listed in each course description. Students must meet the prerequisites to register for a course. Admission will be determined by the Academic Team and the Executive Director of Gravitas. Students who do not currently attend The Stony Brook School or Gravitas will be required to apply through the school's admissions portal. An admissions representative will walk you through the process. You will need to submit transcripts or report cards for the past three school years.

High School Credit
High school courses can be taken for official high school credit from The Stony Brook School or audited for enrichment purposes only. Students will receive a Stony Brook School transcript indicating their grade for the course and the term during which they took it. The tuition for the summer course is the same either way. Students may choose whether they want credit or not upon completion of the course. No withdrawals will be published on the transcript.

Sessions
Each summer session will last three weeks, with students completing the equivalent of one week’s worth of coursework per day. Three weeks at this pace is equivalent to one semester (0.5 credits) of a course. Students may take a maximum of 1 credit per three-week session. Students taking 1-credit courses will schedule an oral exam with their teacher during the week after the class has finished. Students wishing to complete a year’s worth of work will take six weeks worth of class and then will schedule an oral final exam with their teacher during the seventh week.

• Summer A - June 9-27 (0.5 credits/12 live sessions)
• Summer B - June 30-July 18 (0.5 credits/12 live sessions)
• Summer C - July 21-August 8 (0.5 credits/12 live sessions)
• Summer B-C - June 30-August 8 (1.0 credit/24 live sessions)

Cost
Tuition is $1,600 for a 0.5-credit three-week intensive and $3,200 for a 1.0-credit six-week intensive. Students may take no more than one course at a time. Need-based financial aid is available via application. Click here to learn more about our financial aid application. Students enrolled at SBS will automatically receive financial aid proportionate to their existing 2025-2026 school year agreements with the school. Payments will be made through Smart Tuition.
