Frequently Asked Questions

How much does it cost?

It's 100% free! While we certainly hope that you will consider Green Light Education for SAT tutoring following your exam, you are under absolutely no obligation to work with us.

How long does it take?

The SAT Diagnostic Exam takes 47 minutes to complete, including a 5-minute break between the second Verbal Module and the first Math Module.

The timing is broken down as follows:

  • Verbal Module #1: 8.5 minutes
  • Verbal Module #2: 8.5 minutes
  • Break: 5 minutes
  • Math Module #1: 12.5 minutes
  • Math Module #2: 12.5 minutes
Do I have to complete it all at once?

You do not have to take the SAT Diagnostic Exam in one sitting - you'll receive an email after you complete each module with a link to begin the next module.

So, you can theoretically take as long as you'd like between modules (Note: you cannot pause a module in the middle and return to it later).

However, we strongly encourage you to take the exam in one sitting, as this is how you will take the real exam. It's important to consider how fatigue will factor into your exam performance, and taking the exam all at once is the best way to simulate this variable.

What should I bring with me?

We recommend that you bring the following items to your exam:

  • A calculator
  • Scrap paper
  • A pencil + eraser
  • A light snack (to be consumed during your break)
How does timing work?

Each module has its own timer, which is displayed at the bottom of the exam page. You cannot exceed this time, but you are welcome to submit your exam early if you finish before time expires.

We currently only support Standard Time, but plan to roll out an Extended Time version by mid-2025.

Are the results accurate?

Our goal when creating our SAT Diagnostic Exam was to provide the most accurate results possible in the shortest amount of time. To achieve this objective, we had to balance two primary considerations when designing the exam:

  1. The need to project a student's full exam score with a high degree of accuracy.
  2. The importance of providing a similar content composition to the full-length exam.

We've achieved #1 by providing score bands in our score reports - essentially several different projections based on our degree of certainty.

We've achieved #2 by ensuring that the content breakdown is as close to that of the full-length exam as possible.

The purpose of any diagnostic exam is to provide a benchmark from which parents and students can make informed decisions about their preparation process, and we believe that our Digital SAT Diagnostic Exam does exactly that.
