How is the score of an Assessment calculated?

Upon completing an assessment, you will receive a score in the form of a percentage. This score will determine whether you pass or fail the assessment. You will also receive an email that shows how many correct and incorrect challenges you answered. This information can be used to help you identify areas where you need additional practice.

You may notice that the Score is not linear and the percentage doesn't reflect the ratio of correct and incorrect challenges you answered. This is because each challenge within an assessment is weighed differently, depending on its complexity and the size of the code base which explains why challenges will not contribute equally to your overall score.

Factors taken into consideration when the score of the assessment is calculated:

1. Base Score:

Stage	Points
First Stage of the Challenge	100 points
Second Stage of the Challenge	80 points

2. APP Scale (size of the code base):

APP Type	Scale
Full APP	2
Minified APP	1

3. Difficulty Scale of the Challenge

This value gets assigned to each challenge when it's first created

Challenge Difficulty	Scale
Easy Challenges	Difficulty scale <=33
Medium Challenges	Difficulty scale <=66
Hard Challenges	Difficulty scale >66

To calculate the assessment score:

Value	Formula
Stage maximum score	Base points * APP Scale * Difficulty Scale
Challenge maximum score	Maximum score for the first stage of the challenge + Maximum score for the second stage of the challenge
Assessment attempt maximum score	Sum maximum score across all challenges
Points earned in each stage Since users are allowed only one attempt for each stage, and no hints are offered, they either achieve the maximum score for each stage or receive zero points.	Base points * APP Scale * Difficulty Scale
Points earned in each challenge	Points earned in the first stage + Points earned in the second stage
Total points earned	Points earned across all challenges in the assessment attempt
Assessment Score= (Total points earned/Assessment attempt maximum score) * 100

View the weight of each challenge

To view the weight of each challenge, navigate your assessment result screen and scroll down to challenge details, this will outline which questions you had got correct and incorrect as well as the total weight and the weighted score achieved per challenge.

The weight of each challenge = (Challenge maximum score/Assessment attempt maximum score) * 100
