Code Tracing and Readiness Review

Introduction

This is the last lesson of the course. It covers all five sections of PCAP-31-03: Modules and Packages (12%, 6 items), Exceptions (14%, 5 items), Strings (18%, 8 items), Object-Oriented Programming (34%, 12 items) and Comprehensions, Lambdas, Closures, and I/O (22%, 9 items). The exam has 40 questions in 65 minutes, so you have on average about 100 seconds per item, and most items show code. Knowing the rules is necessary, but it is not enough: you must apply them quickly and without mistakes on code that was written to trap a hasty reader.
