Handful of Potential Typos, Exam B02

Hello again! I wanted to flag a handful of potential typos in this new practice exam. If any require further discussion, I'm happy to spin that specific question off into a separate discussion ... just figured having them all in one post might be more efficient. :)

Q8a - question states annual policies, but answer key calculates ARL for 2020 using semi-annual policies

Q9b.iii - question asks for trended AY2020 losses, answer key applies trend period for given historical period of 2024; trend period = 3 instead of 7, unless this is intended to be only the second step of a two-step trend problem?

Q11 - ( 1 + ULAE % ) should likely only apply to L&LAE ratio in the numerator, but answer key has it applying to ( L&LAE ratio + F ); same as in Exam B01

Q13 - answer key seems to have a typo in the final formula for rebased indicated relativity, since lower pure premium should correspond to lower relativity

Q18 - retroactive date of 1/1/22 applied to a 2022 CM policy would limit coverage to the (2022, 0) entry, but answer key includes (2022, 0) + (2022, 1) + (2022, 2); same as in Exam B01

Q24 - answer key's formula for selected latest diagonal in Step 3a (IPS) is pulling in the average for 36mo and 48mo (only impacts 36mo, since avg of one observation is the same as latest diagonal)

If any of these are my own misunderstanding (and not typos), though, please correct me!
