HOW LONG DOES IT TAKE TO FINISH OG11?

OG11 has 800 problems. My general recommendation is 4-5 minutes each question - 2 minutes for doing the problem under timed conditions and 2-3 minutes going over the solutions (regardless of whether you got the question wrong or right). That's 5 minutes X 800 problems = 4000 minutes = 67 hours. If you are really going to study 10 hours per day (which I don't recommend) and only did the OG11, you could possibly finish it in 6 days although I strongly advise against doing so. This last suggestion is because the sheer amount of learning, absorbing and applying what you've learned will probably be too great in such a short amount of time.

Cheers!

I say this because I just finished all the MANGMAT books and I am just starting the extra bins... I dont seem to have the confidence to even start of with CATS sinceI am thrown off with the question bins.

I personally feel that the books kind of gave me a refresher in Maths but not deep enough to seriously challenge 600-700 questions.

I know more practice will lead me there and thats why I thinking ´heck´ - despite the MANGMAT books which uses the OG 11 for exampled questions. Why don't I go through the whole OG11 again? You know, try and wing it in 10-14 days or so.

If it will boost up my confidence, take me above 660 then I will be satisfied. And give away ALL my books to charity (by the way there are over USD 500 worth)

Any thoughts on the strategy, for the next 3 weeks!
