Ramachandran is an excellent professor who clearly cares about her students. Lectures are podcasted, and she really picks some of the best TAs. In addition, she provides several worksheets online to make understanding a little easier. I would definitely take this class again with her. The only negative includes the fact that she oversimplifies her lectures so the material being covered on exams is much harder than what is taught in lecture. For the most part, her midterms are fair, however, I did have an issue with how they are graded, especially the second midterm; I thought the grading was much too harsh(-10 points because my work did not match hers even though I got the right final answer). One other thing to really consider before enrolling is that she covers OCHEM unlike the other 14B professors, and it is as heavily weighted on the final as the other topics. This is an issue because the material is difficult, and she moves at a very fast pace. The other classes are just now covering material we covered in week 6. 40% of your grade is based on two midterms, 40% on a final, and 20% on 3 multiple choice quizzes, graded discussion worksheets, and graded homework/clicker participation. This allows you a guaranteed 20% if you study and just do the work, but if you mess up on one midterm your grade is kinda stuck. My advice is to go over her lecture slides, sit in the front, ask questions when confused (she can come off as condescending, but I do not think she means to, so do not be afraid), watch videos for further clarity, and to go to office hours. If you put in extra work, you will do well, just remember to weigh your options with other professors prior to enrolling. That being said you can not go wrong with Roshini for a solid MCAT Prep chemistry course.
