Help with Nitpicky details in book.

Hi My teacher is giving us a test on the book on Friday, and se has already warned us about nit-picky details that will be on the test such as ages and perhaps the number of times a certain event happens. Could anyone who knows the book very well help me out...

in terms of how many sermons Dimmesdale preaches

how many times Hester and Dimmesdale go into the forest,

How many times Mistress Hibbins appears.

How old everyone is...

I am looking through the book right now trying to figure it all out

Help is greatly appreciated.
