Neuroscience at MIT doesn't let you skip the hard chemistry — River's coursework required genuinely understanding concepts like electrochemistry, molecular polarity, and gas behavior to make sense of how neurons and drugs interact at the molecular level. That means when a high school student is stuck on something like electron orbitals or VSEPR theory, River can explain the underlying logic rather than just restating the textbook rule.

I am also a first year medical student at the Tufts University School of Medicine in Boston. I have extensive experience with premedical classes and have taken and tutored the MCAT exam. I placed in the 97th percentile of the MCAT exam and I understand what the test takers want students to know and how to bridge the gap between knowing the material and doing well on the test. I am always excited when a student finally has that "ah-ha" moment and declares that they now can see how all of these seemingly separate scientific topics are actually all related. The MCAT no longer seems scary, but turns into a means of truly learning this material and providing a strong foundation for the future.
