Hi
I can sympathize with you position, primarily cause I work in a Big 4 too
Ok for starter join a gmat class. U need the kick in the rear to get you off work at least twice a week & study. This is a mistake I did in my initial study plan as well. Work caught up & studying went in the bin. Breaking you leg might just be the silver lining you need to take the GMAT by its horns n bury it once & for all
2. Download the GMAT club flash cards & verbal notes. I have attached a SC guide in this reply. Its super helpful specially if your basics weak.
Manhattan Books are also good & they throw in 6 tests as well. Invest in it PERIOD
3. At least once a week make it a point to give a Mock Test.
4. Review mistakes made by you & others. This forum is the best resource for this. I also mark questions that go beyond my understanding & then the wizards who haunt the alleys of GMAT Club come up with ingenious solutions that make you want to scream & beat yourself for not looking at it in the first place
5. Practice AWA. I know no one does but on D day u be less stressed if you know your way around it
Best of Luck !!!!
