BSAS mock -- What errors did you find?

What errors did you find in the BSAS mock exam? I think the answers to the following questions (all from the PM session) are incorrect, or result from vaguely worded question stems: Q. 18 having to do with a switch from SL to DDB; Q. 27 having to with taxation of dividends Q. 33 regarding FCFF calculation.

Q 58 is an error for sure

wat is ur score on the morning session?
