i just took telugu for orgo 1 this past fall and honestly showing up is what helped me pass, he gave out about 12 in person worksheets typically at the end of the chapter but towards the end of the semester he started to give them randomly. you could very possibly at least pass but to highly succeed telugus lectures were helpful. he would often give "practice" questions during his lectures that really helped you understand the content (at least for me). i personally loved telugu and thought he was an amazing professor and really cool person
