The ugliness of the CIR solution gives me slight skepticism that these kinds of problems will actually be found on the March 2018 exam. Overall, can someone confirm whether or not I should spend significant time on this material, and/or what the most important takeaways from this chapter are?
Thanks for your help.

Vasicek and CIR interest rate models are
no longer on the current syllabus. You are only responsible for pricing interest rate derivatives under a binomial tree for interest rates, including the BlackDermanToy tree. Also, you need to know how to price interest rate caplets, floorlets and bond calls and puts by applying the Black formula.
