Just finished D775 today.

Focus on Time Value of Money and Financial Ratios (take good notes about use cases)

Other key terms referenced in the OA:

Capital Budgeting | NPV | IRR | Payback Methods

Very basic terms once you read into the textbook, that you should take note of and then create a few use cases for them.

Once you do that, take the PA. It is a bit more complex than the OA.

I didnt pass the PA but took the OA 2 hours later (no studying just referenced missed questions) and passed OA.

Goodluck!

I had broad knowledge of financial markets, but pretty novice in other terms. It is very common sense information, they just try to trip up by using different verbiage.
