On the MCAT

Most free body diagram questions will be discrete or pseudo-discrete questions
These types of questions are not necessarily high yield, but often cause distress for test takers, so we like to think of them as high stakes

Testimonial

I think these webinars are really helpful! I like how they’re styled like a TED talk, so they don’t interfere with the day, but they’re really helpful review 🙂

I found everything helpful about these webinars: the explanations, the illustrations, just everything!

Amazing material conveyed concisely and in great detail!

The wealth of information and sample questions are great.

“These 30 minute FREE, live videos conducted each Friday helped me get through the pandemic. Weike is an exceptional tutor, and being able to ask questions after she’s done was magnificent. These webinars have even helped me in class subjects such as Biochemistry. I’m looking forward to starting one-on-one tutoring with Cambridge Coaching, and I’m already feeling confident about taking the MCAT when the time comes.”
