, Foundations of OOP - Classes, Objects,
Abstraction
This section covers blueprint vs instance, constructors, self, class vs instance variables, methods,
abstraction. Essential for WGU D278 PA code tracing. You will analyze instantiation flow, memory
allocation, and how classes encapsulate state and behavior to model real-world entities in Python
and Java-like syntax. Focus on __init__, self binding, and object lifecycle management. This section
contains detailed practice questions aligned to WGU D278 Objective Assessment blueprint
2026/2027. Each question includes verified solution and rationale explaining correct choice and why
alternatives are incorrect. Focus on code tracing, conceptual understanding, and scenario-based
application for PA and OA success.
Study Tips: Review Python docs for foundations of oop - classes, objects, abstraction, practice with
IDE debugger, write small scripts to test. OA weight approx 19.0% of exam. Ensure mastery of
terminology and hands-on coding exercises.
