The OG books are great for practice but not enough to
learn quant from scratch, so start by rebuilding your math basics. Use free resources like
GMAT Ninja and
GMAT Club on YouTube or affordable ones like
Manhattan Foundations of Math. You don’t
need to buy a paid course unless you want structure (
TTP is great but pricey). With 2–3 months of consistent, focused practice, you can absolutely hit a 700+.

Hello, I am a humanities student and haven't done any math (except for day-to-day calculations) in about 8-9 years. I want to score a 700+ on the GMAT. I have all the OG books for 2025-2026. Would these be enough? I took a mock test without any prep and scored a 435. I am really rusty with math and consequently, struggled with both Quant and DI. I have heard
TTP is quite good for quant but they seem quite expensive. Could someone please suggest some resources or give me advice to improve my Quant and DI scores? And do I HAVE to buy a course to improve at Quant or can I get by with free resources like youtube videos? Please help!
