Thank you very much. I finished the number properties book and I just started with the second book of the set about decimals. Do you think I should answer OG questions first from the Number properties book or finish all the guides and do all the questions from all topics. I have only 1 month 6 days for my exam. My math is not as sharp. I need at least 550 score

Finally, do you think I should go over all the

Manhattan books, and give them equal hours? I heard over and over again that the first and the last books of the guides are the best. Do you think I should invest in them the most, and skim over the others, esp the english ones.

Thanks guys your help is so much appreciated
