TECEP Financial Accounting

[Carnation]

Has anyone taken the Financial Accounting TECEP?
I couldn't find any information through search of this website.

The recommended book covers Financial and Managerial Accounting.
Anyone know how much of the book is covered on the test?
Anyone know how difficult the test is?

My son aced the Intro to Political Science TECEP first try, but couldn't manage a pass on Microeconomics with 2 tries (despite reading the 2 recommended books and reviewing multiple courses on Study.com!)
Seems there's a wide range of difficulty in regards to TECEPs.

Any insight would be appreciated.

Should be a decent test to take.
