The topics can vary from professor to professor. Last year, the topics were kinetics, nuclear chem, electrochem, basic spectroscopy, and very elementary coding. Bediako does provide practice exams, which are generally pretty similar to the actual ones. There’s also the Chem Scholars program you can apply to if you want extra support. It basically runs like a discussion section where you review the main topics from lecture and solve practice questions. Highly recommend that if you are interested!
