A FREE CPL Study Tool

I’m pleased to debut my final practice quiz to support students studying for the CPL exam. This last one is dedicated to calculations. Take the quiz here.

The quiz features 45 problems covering:

  • Acreage calculations
  • Net mineral acres
  • NRI calculations
  • Proportionate reduction
  • Farmout and well trade math
  • Promoted deal formulas
  • Cost depletion and percentage depletion
  • Federal lease calculations
  • OCS calculations
  • Interest ownership scenarios

For this quiz, you will find a “given” box on each problem showing all the known values before the questions – just like a real exam problem. After answering, you will see a step-by-step solution box that shows every calculation worked out in full as well as a reference to the page number of the AAPL Study Guide.

These quizzes provide a flexible way to reinforce learning and evaluate readiness. I’ve created five practice quizzes to cover a broad range of topics typically found on the CPL exam. Each quiz features instant feedback, detailed explanations for each answer, and page references in the study guide for further learning.
