Can you point me to these sources? I've downloaded something known as 1000 PS/DS. The questions seem relatively tougher. But my worry is that I don't want to veer off course of what is necessary.
Kindly have a look at
gmat club tests. These are excellent for people who want to jump from a Q45-46 to Q49-50.
MGMAT & other test prep companies have some good Q pool of questions. You can avail those as well. FOC (free of cost) resources are not much helpful in gmat preparation. You can also subscribe the free daily gmat question of the day here on this forum. That is a useful tool too.
Best of luck & let us know in case of any help required.
