Chemistry Web Tutorial

  • Prepare for the Chemistry Placement Exam.
  • Refresh and expand your introductory chemistry knowledge.
  • Get feedback about your level of preparation.

CHEM-Web is a free online tutorial that helps incoming first-year students review general chemistry. It covers stoichiometry, atomic and molecular structure, chemical bonding, solutions, chemical reactions, and thermochemistry.

The CHEM-Web does not exempt students from taking the Chemistry placement exam. The program can help you prepare for the placement exam. The alternative is to take CHEM0100, a semester-long class offered during the fall, then take CHEM0330 in the spring semester.

This tutorial is cost-free and is appropriate for students of all backgrounds.


The CHEM-Web tutorial is open throughout the year.  To access the web tutorial, please email [email protected]. Please provide your full name, and your Brown and Banner ID number.
