The path to many of the most sought-after majors, from pre-med to engineering, generally leads right through General Chemistry--and for many students, this challenging "weeder" class can be where that path stops, too. Turn Gen Chem from a gatekeeper to a gateway with weekly, expert-led classes as you review and preview concepts pertinent to your place in the semester. Each week, an expert instructor will guide you through key concepts and problem-solving strategies, giving you the tools you need to excel in your chemistry courses. From balancing equations to understanding reaction mechanisms, we've got you covered.
