I worked very hard over the last year for GMAT. Unfortunately I was barely able to cross the 600+ mark. The results were dismal compared to the labour that I had put in. This has shattered my confidence. However, I have picked myself up and plan to give it another try this year. I need some sure-success mantra.

" I need some sure-success mantra."
