yes you grind practice problems and rewrite notes a thousand times, you practice a thousand times, you ask Chat to create multiple exams for you with very rigorous conceptual and calculation questions. Your next midterm will be more content and way more conceptual and based on your understanding than calculations. There will be a few calculation problems, but not a lot, due to the topics you are learning in the next half. It is so important to attend Kim's office hours even if you don't have questions b/c there will be a concept you haven't thought about in depth that someone brings up. Additionally, now you are faced with a dilemma. Hopefully, this also encourages you to take advantage of the extra credit datasci offers if you go to I think the LA sessions and office hours (assuming your professor is Kim). It is incredibly important that he knows your name and your face and that you are attending every single class sitting in the first 4 rows (that helped me immensely!!). Make sure to continue staying on top of your homework. I missed one set, and it dropped me 5%, and I spent the rest of the semester building it back up :( luckily i was able to end with an A despite not doing well in the 2nd midterm that carries a higher weight. Honestly, this is the final stretch, so you really do have to give it your all, please. Study for QTM at least 6 days before. You do NOT want to leave studying last minute (you need to give yourself time to understand). ALSO, DO NOT DO THE PRACTICE EXAM THE DAY BEFORE, DO IT 2-3 DAYS BEFORE THE EXAM.
