I have completed “I am Overwhelmed Quant Mountain”
Now , Can anyone say where to practice Quant from ?
I am focusing on Gregmat Medium & hard questions mainly , is the difficulty same as Real GRE?
Also Topic wise practice (especially Data Analysis) – where can i find them?
Yes, but some might disagree. Regardless, they are very good practice material especially because ETS materials are at a premium. Doing Gregmat questions ensure you don’t waste the official materials for your later prep.
On the last point, be sure to transition to official materials when getting close to your exam - you need to build enough familiarity with ETS official questions before the real thing.
For now, you can focus on the highlighted box above.
