Math for the March 2026 SAT

    Mondays 2:00 AM, Saturdays 9:00 PM

Hi! I am a 12th-grade student in both a general and technical high school, specializing in cybersecurity. On Schoolhouse, I've provided 1-on-1 and group instruction in Calculus, Computer Science, Linux, and SAT prep. I'm in the top 10% of tutors for hours spent tutoring and sessions hosted. I've also been a longtime math instructor at Mathnasium; I worked at 8 different locations from 15 years old to now, providing instruction for students from 4 years old to 18 years old. Besides tutoring, I am developing a Python curriculum for a nonprofit supporting marginalized genders in computer science, actively competing in SkillsUSA cybersecurity competitions, and serving as a Linux specialist on my CyberPatriot team, working with multiple Linux distributions. This four-week tutoring series will help you prepare for your upcoming SAT in Math. By the end of the series, you will have completed multiple practice tests and worked through a number of problems from previous SATs, helping you build confidence for your upcoming exam. You’ll spend each session with me and a small group of other learners who are also working towards taking the SAT. Since it’s a small group, you can expect sessions to be very interactive as you work together towards improving your SAT skills as much as you can! Note: Cameras should be on so we can all get to know each other! If you have a specific reason why you can’t have your camera on, please notify me ahead of time.

keywords: linux, scripting, system hardening, vulnerability management I strongly encourage anyone preparing for CompTIA Security+ or looking to dip their toes into cybersecurity or network security to join this series. This series will meet every two weeks (on a weekend), and topics will be decided and discussed in the series group chat. Topics will revolve around ethical hacking, penetration testing, and network security. Anyone is welcome to join at any time in the series as there will be a new topic done every session and any necessary prerequisite knowledge for said topic will be shared prior. I’m in no way a cybersecurity professional; I’m just 17 years old, but I hold CompTIA A+, Network+, and Security+ certifications, as well as Cisco Linux Essentials and EC Ethical Hacking certifications. I’m currently working towards my Cisco CCNA certification and preparing for the CyberPatriot and SkillsUSA Cybersecurity competition.
