Challenger School moves quickly, and a new concept can sometimes feel like a big jump. Our tutors are current and former Stanford students who are patient, clear and good at explaining things more than one way until it clicks.
We help Challenger students keep up and get ahead in math, reading, writing and science, and build good study habits early. For 8th graders applying to independent high schools, we also offer ISEE, SSAT and STAR prep.
What parents say
“My daughter went from a C in Algebra II to an A- in one semester. The tutor was great, she really related to my daughter and made learning fun for her. Not only did her grade in math improve, her study habits improved and she’s doing better in all of her classes.”
Eduardo S., San Francisco
“The tutors themselves have been great: well-prepared, thoughtful and on-time. At each level of math needed, we found these Stanford students to be not just helpful tutors but great mentors as well. … This is a first class operation.”
Christy S., Portola Valley
“My son was a senior this year and I reached out to Cardinal Tutors and was lucky enough to find the most amazing tutor. I wish I had found him earlier.”
Sharon C., Los Altos
