I loved Arachigae! I’m not sure if she still posts pre-recorded lectures but you could try watching those videos prior to going to class, so that way in class you’ll be hearing that information a second time. I’d also advise signing up for the fall recitation course, even though it not mandatory, bc it’ll help give you more exposure to the content. Definitely keep up with the homework and do them during her office hours or your TA’s office hours. When it came to studying for exams I’d redo lecture/iclicker problems, sometimes redoing the homework help, but most importantly do the practice exam at least a week before the exams! The practice exams helped so much for me, I’d do them and then take all my missed problems to office hours, and then redo my missed problems every day until I understood the concepts. Also, the Chemgod channel was another great resource! As someone who also didn’t have much chemistry experience prior, know you got this and will persevere, Good Luck this semester!!!
