APV

hi sir
im facing some problems with the rationale of APV calculations in general.
ive attempted the questions in the bpp kit for the first time , and am finding most of the numbers alien . but thats bcause its my first time maybe thats why.

but mainly ive tried to attempt example 2 for APV from Ch 12 the impact of financing in your notes, but the recorded lecture is not about APV. its mainly talking about miller and modigliani theories.
main questions:
a)could you tell me where you have recorded the APV lecture please?
b)any suggestions as to how to tackle APV please.
c)can APV be expected within a 50 mark section a question.

thanks alot
