ОК, на этой неделе встреча отменяется!!!

[Snare]

некст тайм может и я подгребу. keep me informed pls
а пока скажите где прочитать про комбинаторику и вероятность

[crosswall]

подскажите плиз, над чем из вышеуказанного надо работать в первую очередь, а что может подождать или даже сойти с рук.

Да желательно все почитать, это не так много, как может показаться. Хороший способ - прорешать задачи из OG11 и рассмотреть все решения. На экзамене по quatitative не будет ничего нового, все то же, что и в OG. За неделю легко можно справиться.

а пока скажите где прочитать про комбинаторику и вероятность

Освежить можно почитав основы в gmatprep, если все несколько хуже, то посмотреть можно в Принстон Ревью, а может и в Барронсе все есть (я не знаю, не имел последний).

15. If n is a positive integer, the sum of the integers from 1 to n, inclusive, equals n(n-1)/2. Which of the following equals the sum of the integers from 1 to 2n, inclusive?
(A) n(n + 1)
(B) n(2n + 1)/2
(С) n(2n + 1)
(D) 2n(n + 1)
(E) 2n(2n + 1)

Камрады, вам ничего подозрительным в условии задачи не показалось?
Я опечатался сорри, сумма конечно равна не n(n-1)/2, a n(n+1)/2
Теперь решайте по новой, ещё раз сорри, но и вы то же молодцы... как и я...

очередной пробный GMATPrep™ тест показал 620. маловато будет. посмотрел ошибки - примерно 1/3 допустил по невнимательности, остальное - по чистосердечному незнанию . скоро запостю некоторые вопросы. p.s.GMATPrep™ почемуто не дает разбор ошибок, по крайней мере у меня так
