Finally passed my QFC exam after two attempts — what actually helped

So I just got my results back and I passed the QFC on my second try, and honestly I'm still a little in shock. Failed by 8 points the first time around and I was devastated. Spent about 6 weeks prepping before my first attempt using just the official materials, which clearly wasn't enough. The quantitative and fixed income sections completely wrecked me.

Before my retake I switched up my approach entirely. Found a solid QFC practice test online that actually mirrored the real question style — multiple choice with scenario-based questions that force you to apply concepts rather than just recognize them. That made a huge difference. I also built out my own study guide covering duration, convexity, yield curve strategies, and credit risk. Took me maybe 20 hours of focused work over three weeks.

For anyone currently preparing: don't underestimate the fixed income math. I kept getting tripped up on bond pricing under different yield scenarios. Work through the calculations by hand at least a few times before you rely on shortcuts. Anyone else have exam tips that helped them get over the finish line?
