Has anyone found effective online support for preparing for a chemistry exam? I recently started helping with a college environmental project, and balancing those responsibilities with my classes has made it difficult to follow my usual study schedule. I am reviewing chemical reactions, stoichiometry, and atomic structure, but I still need more practice solving calculation-based questions. While searching online, I typed take my chemistry exam for me as I explored different academic support options. I am now looking for legitimate chemistry tutoring, practice tests, and step-by-step explanations. Which study resources would you recommend for chemistry exam preparation?
