[dutchman]

Provider: Straighterline
Course: Calc II
Course content: No textbook. Material is presented through Thinkwell calculus videos with Edward Burger and then practice problems via ungraded quizzes. The course consists of four-chapter tests, 1 midterm, and a final, which are all timed. You can retake the first exam as many times as you want up to the point of taking the final exam which is proctored.
Final exam content vs course content/practice exams: The difficulty of the final was consistent with previous chapter test material.
Time taken on course: I worked on this course regularly for almost 5 weeks.  
Familiarity with subject before course: I finished Calculus I just prior, which made the transition into this material easier. Much of the course expands on concepts and ideas from Calc I with a significant branch into the world of sequences, series, and summations, bookended with a several chapters involving polar coordinates and vectors. The course also covers other topics but lesser in breadth. Comparing it to Calc I, be prepared to take finding limits, trigonometric substitutions, and evaluating definite integrals to the next level. Again, Professor Leonard is helpful for some aspects as well as Patrick JMT who is also on YouTube. Navigating this course is different than Straighterline’s Calc I course, and I had the same frustrations regarding how much work was shown and consistency for worked out problems on practice quizzes.           
1-10 Difficulty level: It’s no doubt a difficult course, dutifully a 9 from me.
