How many stars have I earned?

When training in BrainHQ you will accumulate stars as a measure of your overall progress in each exercise.

In this article we'll cover:

• Finding Stars Earned
• Checking your performance
• Star Overview
• Star Map
• How BrainHQ calculates stars

Finding Stars Earned

You can find the STARS EARNED page by doing the following:

1. Go to www.BrainHQ.com in your browser
2. Click on the "Progress" tab at the top of the screen (taking you to the progress overview page)
3. Click the tab at the top of the screen called STARS EARNED

Note that this information is only available through BrainHQ on the web - the graphs are not yet available for BrainHQ on mobile devices.

Checking your performance

In the Stars Earned section of your progress page you can see how many stars you've earned on each BrainHQ level you've completed.

Star Overview

On the left side of the screen you will see a breakdown of how many stars you have earned in each suite in the Star Overview.

This graph adds up all of the stars you've earned in each exercise suite - Attention, Brain Speed, Memory, People Skills, Intelligence, and Navigation - so you can quickly see what areas you've earned the most stars in.

Star Map

On the right there is a map showing which levels you have earned stars for.

The larger the circle, the more stars you've earned by repeating that level. You can hover over individual boxes on the Star Map to see how many stars you earned on a specific level.

If there are levels you want to train with, you can click on a space on the map to bring up the exercise.

How BrainHQ calculates stars

The stars are based on your score for a given level compared to all of the other scores by other people on that level. From there BrainHQ sets a normal curve, and then awards stars depending on where your score falls within that curve.

On a normal curve, we can expect the following:

• 1 star is below -0.5 standard deviations
• 2 stars is between -0.5 and +0.5 standard deviations
• 3 stars is between +0.5 and +1 standard deviations
• 4 stars is between +1 and +1.5 standard deviations
• 5 stars is above +1.5 standard deviations

As long as you answer at least one trial correctly in a level you will be awarded one star.  If no trials are answered correctly then training on that level is not saved.  

Generally, 50% of people will score 2 stars on any given level. However, by default, the Personal Trainer requires a score of 3 or more stars before graduating to a more advanced level. BrainHQ is designed to be challenging in order to tap into your brain's ability to change—its plasticity—with the goal of improving memory, attention, and other cognitive abilities.

Additionally, there is no upper limit to how many total stars you can earn. Each time you train with an exercise level you have the potential to be rewarded with more stars. If you go back and retrain with a level you've already earned four stars in and earn four stars again, you are credited with the extra four stars from your additional training. All of the stars you earn from training are cumulative and are shown in total at the top of your Stars Earned page.
