How hard is the SAFE MLO Exam?

The National Test (SAFE Mortgage Loan Originator Exam) is definitely not a cakewalk, and we know that. According to the 2018 NMLS Pass Rate Announcement, about 59% of test-takers fail on the first attempt. We are here to make sure that you are fully prepared to pass the test on your first attempt, and our instructors are here to check on you to make sure that you are completely understanding every topic and every piece of information.

What if I am unable to attend a class?

We understand that life happens and we will be happy to reschedule your class to another time at no additional charge.  If the class needs to be rescheduled multiple times, there will be a fee of $25.

What is the difference between online self-study and online instructor-led courses?

The NMLS allows continuing education classes to be delivered in an online self-study format so students can complete them at any time.  However, pre-licensing classes are required to be completed in an online instructor-led format.  This means that an instructor is on staff during specified class hours when activities are viewed and approved in order to progress through a course.

What makes Diehl's 20-Hour course better than others?

Diehl has developed a P.A.S.S. formula that stands for "Preparation, Assessment, and Studying Strategies".  By actively participating in class, reviewing material and test prep questions from our national test prep tool, and interacting with our trainer during class as well as the free study session following the live stream, we are confident you will pass the SAFE Mortgage Loan Originator Test on your first attempt.

How long should I study for the SAFE Mortgage Loan Originator Test?

We recommend you study at least 40 hours to prepare for the SAFE MLO Test. Remember, the overall pass rate averages under 60%.
