Dude, the title of the thread should be how many hours and not how much hours. So you can start with SC. Regarding CR see the link below.

I would ask, what do you mean by "finish"? Simply completing all the questions?

We need to remember to always stress QUALITY of study over QUANTITY. Just because you do every single question in Powerscore CR, does not mean your score will automatically improve.

You'll want to spend a lot more time reviewing the questions than answering them, so depending on how much time you want to spend, personally, on review, there's a huge difference in the amount of time it could take.

I'd make sure you have a focused study plan first, and a clear idea of how you want to utilize your study materials, and how you want to create an Error Log for review, before launching through book after book.

That said, Powerscore CR rocks. Good luck!

Thanks vivian & Abhi..

Vivian how should one do the review process effectively?. Currently what i am doing is putting all the questions which i got wrong in an excel and just review it after 1 week to check if i am again getting it wrong or not. Would appreciate any further inputs. The reason why i posted this topic was because i din't wanted to rush through or spend too much time in covering the subject.

Usually if you spend like 2 hrs (1hr study and 1hr OG practice and review) then 2 weeks should be fine....

But to add an exception to this my friend finished it in a week with 3 hrs of study.....
