Melissa Maribel
High school and college chemistry can feel like learning a new language, and Melissa Maribel’s videos act like a friendly translator. On her YouTube channel and website, she breaks down topics like stoichiometry, acids and bases, and electron configurations into step-by-step explanations that feel more like sitting with a tutor than watching a lecture. Drawing on her experience helping students pass difficult chem courses, she highlights common mistakes, test tips, and visual tricks that make dense material more manageable. Teens appreciate her relaxed, encouraging tone and clear organization by topic and exam. The core videos are free, with optional paid study guides and courses for deeper review, which makes this an excellent first stop for extra help. For best results, watch with notebook in hand and pause often to try sample problems before hearing her solutions.
