Thanks to e-gmat, It started my improvement

I had studied with books of Kaplan and Manhattan about 6 months and I had improved from 440 (V9, Q44, Manhattan 21 march 2015) to 560 (V17, Q50, Official GMAC practice 1, 20 September 2015), but in the next 5 months, I wasn't improved my score, and it was flat with a constant 540 (V19, Q49, Veritas, January 9 2015).
For this reason I took the e-Gmat online Verbal, and in 4 month I improved to 650 (V27, Q49, Official GMAC practice 2, 30 April 2016). The may 10 I took the real Gmat and i get 620 (V27, Q49). After, I took a little "days off" (start university application and took the TOEFL), and today I start the way to get more score with my best partner, e-Gmat, the next 5 of September.
