How hard are the cap rate and DCF modeling questions on the REA exam?

I'm a few weeks into my real estate exam prep and the quantitative sections are tougher than I anticipated. The cap rate questions seem straightforward — NOI divided by asset value — but the exam appears to test edge cases like reversionary cap rates, going-in vs. terminal cap rate spreads, and sensitivity analysis on exit pricing assumptions.

The DCF modeling questions are where I'm struggling most. They require you to hold multiple assumptions in your head simultaneously: rent growth rates, vacancy assumptions, capital expenditure timing, and discount rate selection for different real estate investing strategies. It's closer to what I'd expect on a financial modeling test than a general knowledge exam.

I've been using the REA Financial Modeling and Investment Analysis quiz to practice the calculation-heavy items. Some questions give you a partial pro forma and ask you to identify the error, which is a smart format but genuinely difficult.

Is the property valuation section similarly quantitative, or is it more conceptual? Trying to allocate my remaining study hours efficiently before the exam date.
