How do I get faster at comparing numbers for a quant interview?

Practise deciding which of two quantities is larger without fully computing either - compare orders of magnitude, cross-multiply fractions, and estimate. NeetQuant's Which Is Larger? drills this across fractions, powers, roots, and factorials under a timer.

Do I need to compute both values exactly?

No - that's the point. Strong candidates decide by structure and estimation (cross-multiplying, comparing exponents, order of magnitude) far faster than exact computation. The hard rounds are close enough that only quick estimation gets you there in time.

Is Which Is Larger? free?

Yes. It's free to play with a NeetQuant account; Premium adds configurable counts, timers, and difficulty.

Number-Sense Speed Drill for Quant Interviews

Which is larger? Call it without fully computing - the number sense trading speed rounds reward.

Speed rounds at trading firms reward number sense: seeing at a glance that 3^5 beats 5^3, or that 7/12 edges out 11/19, without grinding out the exact values. It's the instinct that lets you sanity-check a price or a size in a fraction of a second.

Which Is Larger? drills exactly that. Two quantities appear - fractions, powers, roots, products, percentages, factorials, combinations - and you call the bigger one by typing 1 or 2, against the clock. Easy rounds are clearly apart; hard rounds are deliberately close (6! vs 3^6 is 720 vs 729), forcing real estimation rather than eyeballing.

What it's modelled on

The rapid number-sense checks common in trading speed rounds

Trading interviews and speed rounds lean on fast comparison and estimation - deciding which quantity is bigger without computing both exactly. This trainer isolates that instinct across fractions, powers, roots, and combinatorics, with difficulty set by how close the two values are.

What it trains

Fast magnitude estimation without full computation
Comparing fractions, powers, roots, and factorials by feel
The sanity-check instinct that catches a mispriced or mis-sized number

How it's scored

You type 1 or 2 for the larger quantity; you're scored on how many you call correctly within the timer. Premium unlocks configurable question counts, timers, and difficulty - from clear gaps to razor-close calls.
