Parallelogram Method vs. Extension of Exposures

I went through most of adapt but this is an area i always have a problem with. When doing adapt quizzes / tests, i end up using the formulas and have not really seen the parallelogram method / extension of exposures used. Can anyone point me to a resource / adapt question that uses these methods so i can better understand how they're applied?

Thanks

Take Adapt quizzes on "4.3 Ratemaking" at target difficulty 6-8 and you should get parallelogram/extension of exposures method questions.

The STAM sample questions released by the SOA also contain a couple questions on the parallelogram method. They're questions #314 and #317.

This info is helpful Terence. I've been working on quizzes, wishing I could get ADAPT to give me more granular choice over topics such as the parallelogram method. Could you give a similar recommendation of a difficulty range for questions that test conjugate prior concepts in the Bayesian Credibility section?

@HealthHoncho, I got conjugate prior concepts in quizzes around level 4 - 7. They're usually in the 5 - 7 range.
