Fixed income has one of the highest potential weightings so I would not do that. Just try and get through the material quickly and gather as much low hanging fruit as possible if you really feel like you don’t have enough time.
Memorize the definitions/qualitative stuff/simple formulas 1. differences between structural and reduced-form credit models 2. differences between ho-lee/cir/vasicek models 3. differences between different interest rate expectation theories 4. learn meanings of spreads (TED spread, libor-OIS spread) 5. memorize CDS formulas also helps if you can memorize effective duration, and convexity formulas (and learn what they look like for bonds with embedded options). based on the practice questions, mocks, and EOC questions, binomial tree valuation is a must-know. if you skip this, you’re likely giving up 1-2 questions on the exam.
If you’re running out of time, leave Derivatives if you’re weak at it. It weights for about 5-15 and just 3 brain storming readings. I’d rather work on other readings where I know i can make a difference than waste time on it only to end up understanding nothing. Just my opinion.
