I’m a passionate and results-driven tutor with a college GPA of 4.0/4.0 and a high school GPA of 4.26/4.3, and I know exactly what it takes to help students reach the top.

With over two years of tutoring experience, I specialize in helping students master challenging topics in math and science. I’ve tutored peers in high school and college, and now I work with students online across the U.S. to improve their confidence, clarity, and problem-solving efficiency. My lessons are concept-driven and customized to each student’s learning style.

I’m bilingual in English and Mandarin Chinese, making me especially effective with international and bilingual students who may benefit from instruction in either language. I currently offer flexible online tutoring for subjects including Pre-Calculus, AP Calculus, Chemistry, and Physics.

I look forward to helping more students succeed—whether they’re preparing for AP exams or simply aiming for a higher GPA.

Knowledgeable, patient, and hardworking

Changlin is always 5 minutes early to every class with the lesson plan and explanations ready. Chemistry is a hard topic, but thanks to him, I can comprehend it. His assignments and documents do nothing but reinforce what I learn in Chemistry and hope to keep tutoring with him.

Great teacher!

After three sessions with Mr. Changlin, my Pre-Calc tutor, he has been very patient and helpful. He works through problems with me, lets me try on my own, and I’ve already seen my grades improve. Highly recommend!

Very Knowledgeable and patient tutor!

Changlin took his time with our 10 grade daughter who needed some help with chemistry. He was very knowledgeable and showed her how to understand the concepts she was struggling with. Highly recommend!

Steven C, 1 lesson with Changlin

Great tutor

Changlin is a great tutor! When we did our first session together, since math isn't my favorite subject he made it so easy for me to understand the problems of what's asking. He wants to make sure if the questions are understandable and correct before we go to the next problem. I'll definitely recommend him being my tutor again
