There a few YouTube Channels I highly recommend taking a look at during your studying!

Chem/Physics/Orgo (section 1 on MCAT)

• OrganicChemistryTour Youtube Channel (great for learning all the concepts)
• https://youtu.be/F23R6UKcCRM?si=fVpn2_D1sjK2mjbu (Watch this for Mental Math tricks)

Bio/Biochem (section 3 on the MCAT)

• AK lectures (great for biochemistry, especially for Enzyme + Michaelis-Menten stuff)
