Cliif Notes and Coles Notes are always helpful to fully understand and appreciate literature to it's fullest. I finished Crime and Punishment a few days ago and found this online.
It points out all of the contrasts, character development and foreshadowing thst an average reader usually overlooks. I would always follow up any books with the Cliffs Notes summaries if they are available.

I remember almost none of reading Constance Garnett's translation in my teens and was not looking forward to re-reading it or either the Richard Pevear and Larissa Volokhonsky or Michael Katz translations. James Roberts's summary did an excellent job, an absolutely delightful read.

I always enjoy Cliff Notes summaries as a short course on important books. This one also fit that mode.

Helpful in learning characters, with their multiple Russian names, & revisiting each Part of the story.
