Integreted Math 2 or Algebra 2? How long will they take?

I am taking a final exam on Math 2. In 40 days. I know math 1 very well. If I am trying to cover almost everything in Math 2, what course should I do; Algebra 2 or Integreted Math 2? Also, could you tell me how long each of those would take INCLUDING the videos, quizzes, practices, unit tests, etc. I only have 40 days before my exam so I just want to make  sure I can finish  it by then and understand everything.
