Online Live Classes for US & British High School Chemistry Curriculums

Are you a homeschooler who wants to outsource the teaching of high school chemistry to a certified pro?

Do you want to make sure your child learns the right way and achieves the top level required for Pre-med or STEM majors?

I've been teaching and tutored chemistry for over 28 years and got my students to ace chemistry and thrive in med school and engineering colleges.

I can help your child learn chemistry fast and build strong study skills with the clear and no-fluff ACE CHEM Method I've developed in all these years. My classes and programs are HANDS-OFF for parents so they can reclaim this time for themself and their families.

Get your child to study chemistry from the comfort of your home, at a time that fits their schedule, and with my continuous feedback, accountability, and professional evaluation.

NO CURRICULUM is required as I make available my own curriculum, online platform, and learning materials to my students.

The lessons are LIVE so your children can ASK ALL THEIR QUESTIONS and learn and exercise with my FULL GUIDANCE guidance and receive IMMEDIATE FEEDBACK.

This way they'll build confidence and enjoy the learning as they feel they're doing great work and receive grades for their assignments and test. For parents, this translates into lots of free time, no stress thinking they have to teach or help, amazing peace of mind, and always be informed and up to date with the child's level and progress towards their goals.
