I just took place the core and the gas heating air service for Nate yesterday and the first 50 core questions are in the test but none of the gas heating questions are on the test so therefore I only pass the core! I NEED ADVICE

Developer Response ,

The first 50 of the Core, and first 100 of the HP section are the actual questions that will be on the service test. The rest are a collection that have been on the test, or that require the same formulas that will be on the actual test, or that I've collected from around the internet.

Be careful I have found at least 3 questions in this app that are with incorrect answers.

1 what separates the high side and low side voltage question
2 the smallest basic partial of an element question
3 heat pumps will lose efficiency when ambient temperatures drop
4 with schematics what separates the high voltage and low voltage
