How to prepare for GRE Quant in 15 days if I’m starting from scratch?

Question

Divakshi Arora · Accepted Answer

Preparing for GRE Quant in 15 days from scratch is doable if the plan is clear, structured, and focused on high-frequency topics first.
Start with basic Arithmetic&mdash;percentages, ratios, averages, and number properties. These appear the most and build a foundation for tougher problems. Spend the first 5 days watching topic-wise concept videos (GregMat or Manhattan) and solving 15&ndash;20 questions per topic. By Day 6, shift to Algebra and Word Problems. Avoid jumping into tough questions too early&mdash;focus on accuracy.
From Day 10 onwards, switch to mixed-topic practice sets. Time yourself for 35 minutes per set of 20 questions to build pacing. Use a notebook to log every mistake with a short note on why it happened. Review this daily. In the last 2&ndash;3 days, take at least two full-length mock tests and analyze not just scores but patterns&mdash;what slowed you down, what types were consistently wrong.

Starting Quant from scratch with just 15 days left feels stressful&mdash;but a focused routine can push scores up faster than expected.
&bull; Begin with a 3-topic-per-day rotation: Arithmetic in the morning, Algebra in the afternoon, and Geometry/Word Problems in the evening. Stick to just 1 hour per slot. &bull; Use free resources like Magoosh, Manhattan 5lb, or TTP topic drills&mdash;avoid switching between platforms. &bull; For every concept learned, solve 10 questions immediately. Then revisit the same 10 two days later without notes. &bull; Keep a &ldquo;mistake sheet&rdquo; with three columns: Topic, What Went Wrong, How to Fix It. Review it before each session. &bull; Skip Probability, P&C, and harder Coordinate Geometry if time runs tight. They show up less often and cost more time to master.
Focusing on repetition, spaced revision, and time-bound sets is the fastest way to go from zero to a solid GRE Quant base.
