Tips for passing the contractor license exam

Passing the C4 contractor license exam requires strategic preparation and focused study efforts. Here is some study advice from a top student from Harvard:

Know what topics are covered in the test: The C4 exam is broken down into different topics and not each topic is the same length.  Make sure you know what topics are covered and study each topic proportionately to what is on the exam.  To see what topics are covered, click here.  

Take a practice test first: Take a practice test to understand which topics you are strong at and which topics you need to focus on more.  

Learn one section and then practice questions related to that section to make sure you you fully understand the material: Study one section at a time and test yourself after to make sure you fully understand the material

Work backwards from your exam date and set up a regular study schedule: Life can get busy and studying for the exam can get deprioritized.  It is important to understand 

Do several practice exams in the last few days before your exam date: In the days leading up to your exam date, take a few practice exams end to end.  This will help give you a sense of how long the test takes because mental fatigue is real!  It will also help reinforce the material that you learned and reveal if there are any areas that you are weak on so you can focus on re-learning those materials before the test.  

When taking the test, do not spend too much time on any one question if you get stuck: The exam is timed so if you are stuck on a question, move on after 1 minute and go back to it if you get the chance.  The last thing you want is to get stuck on a question and run out of time at the end of the exam to finish all the questions.
