Our Mission
Bringing academic excellence to every student
Our mission is to bridge the gap in school resources by providing exceptional academic support and instruction. We strive to ensure students transition smoothly to high school while encouraging them to delve deeply into their areas of interest. Our team of instructors, hailing from prestigious universities from around the United States, is dedicated to helping students uncover their passions and emerge as leaders in their chosen fields.
Our Story
With the goal of expanding academic opportunities for more students, the club leaders of the Basis Independent Silicon Valley USABO Club launched the BioBrawl biology competition in May 2024, featuring eight teams and over 40 participants. Building on this success, we soon founded HelixEd to broaden our educational offerings beyond biology by introducing online summer courses in Physics, Biology, Chemistry, and Economics for middle school to early high school students. These courses are taught by instructors from top universities and supported by high school TAs with excellent academic records, creating a vibrant and supportive learning community. Since its inception, HelixEd has grown into a thriving community, providing valuable educational experiences to an increasing number of students.
