Why Generic Practice Tests Don't Work

Most GMAT practice tests give you a random mix of everything:

20 questions on topics you've already mastered

Wasted time

2 questions on the topic you're weakest in

Not enough practice

No control over difficulty

Too easy or too hard, never right

No feedback on patterns

Just a score, no insights

You don't need more practice. You need targeted practice.

What Students Say

"I was scoring 155 in Quant because Data Interpretation killed me every time. I built 10 custom tests focusing only on DI. Two weeks later, I'm hitting 80% accuracy. This feature alone is worth it."

Karthik R.
GMAT Quant: 163

"The topic-wise breakdown changed how I study. I thought I was bad at 'Verbal' but really I was just bad at Triple-Blank Text Completion. Now I know exactly what to practice."

Meera S.
GMAT Verbal: 158

"I used to waste hours on full practice tests. Now I do 15-minute targeted sessions on my weak spots. Way more efficient."

Aditya P.
GRE: 322
