Be able to identify messages, literals and evaluating basic expressions is really important. If you only miss a few answers, it is not a big deal. They will come with experience. My advice would be to not only re-read the book but use Pharo playground / inspector in the same time to try the examples and find out similar ones. Regards, Christophe
