| I think you're on the right track, and clearly you know what you need to do. Which is basically: allocate as much of your time and energy as it takes to get the best grades you possibly can. If you can pull off all As between now and graduation, great. If not, try for as many as you can. Cut out any and all extracurricular or leisure commitments that you think will stand in the way of making the grades. And definitely don't take on any new clubs or extracurriculars at this point in the game.
You'll definitely want to get some work experience (WE) under your belt after graduation, regardless of how the grades turn out. Even if they turn out for the best, you'll still want and need the WE. And the high GMAT. You can't really compromise on any of the three fundamentals (GPA, GMAT, WE) when shooting for a T1 or even a T2 school. And to be frank, T1 is going to be very difficult with your GPA even if it turns out to be your best-case scenario. A lot will be riding on your getting the best GPA you can get, scoring the highest GMAT you can score, and getting some solid -- hopefully exceptional -- WE under your belt. At least a few years' worth.
The average age of a b-school applicant is roughly 27, give or take a year at any particular school. So you have some time to turn things around. Just work your butt off, don't slack, don't let up, and stay focused. |
