Hi, I'm Celeste,

the Founder and Chief Instructor at Cygnus Test Prep!

I am a self-proclaimed test prep geek with the heart of a teacher. I am a National Merit Scholar who scored in the top 1% on the ACT, SAT, and PSAT in high school, and I have almost 3 years of experience equipping high school students to ace these exams too. I created Cygnus Test Prep because I believe students thrive best (and thus maximize scores!) when they are known and supported as individuals with a customized prep plan designed to capitalize on their strengths, refine their strategy, and boost their performance. That’s why a Personalized Coaching Package comes standard with every Cygnus group class and also why my classes are capped at a small number of 10 students. In addition, if ultimate flexibility and personalization is your goal, I offer a variety of private tutoring packages that deliver expert test prep instruction in a one-on-one setting.

I bring to every class my enthusiasm, extensive knowledge of the tests, top-notch teaching ability, and a genuine care for my students. I have a proven track record of helping students reach and exceed their score goals, so if you are reaching for the stars, I’m here to help you succeed!

My Approach

Official Practice Tests

My curriculum is built on official ACT, SAT, PSAT, and ISEE content, the gold standard in test prep.

Your instructor makes or breaks the test prep experience. Rest assured knowing you will work a seasoned tutor who knows the test inside and out. I aced these exams while a student myself and I have helped countless others ace them too.

My elite test prep raises scores. If you don't see a score improvement, you will earn additional tutoring free of charge.
