HOW THE MARKING SCHEMES WORK

The marking schemes determine the algorithm used to score the users exams. We currently support four marking schemes.
E-testpedia Exam Marking Scheme 

  • HEURISTICS: This is the default and recommended marking scheme. By this algorithm, each question has a difficulty level which is determined by the number of times it has been passed compared to the number of times it has been attempted globally. This difficulty level indicates the points accorded to that question in the exam. 
  • STRICT NEGATIVE: With this marking algorithm, a certain percentage is deducted from the overall score of the user. This percentage is proportional to the number of questions the user missed in the exam. As the name implies, the deduction is strict 
  • SOFT NEGATIVE: This works in a similar way to the Strict Negative except that the percentage deduction is smaller. 
  • SIMPLE: This marking algorithm is as simple as its name. The total score of the user is the ratio of the number of questions passed to the total number of questions with no deduction. 
HOW QUESTIONS SKILL LEVELS (DIFFICULTY LEVELS) WORK

The Skill Level of  a question is dynamically assigned to it. An Algorithm is used to assign this skill level based on the number of times it has featured, the number of times it has been attempted and the number of times it has been passed.

Thus, a question whose pass to attempt ratio is high is deemed simple hence is rated low in Skill Level compared to one with a low pass to attempt ratio.
HOW RATE OF PASSES WORK

'Rate of passes' of a user is defined by how many questions the user gets right per minute. The unit is Questions Per Minute (QPM). It is used to compute Speed Improvements.

HOW RATE OF ATTEMPTS WORK

This is the rate at which the user attempts (whether passed or not) questions. It is also measured in Questions Per Minute (QPM). A user that has a very high rate of attempt but a low rate of passes is probably (but not necessarily)

  • guessing
  • not taking time enough to read through before answering
  • jittery or not in the right state of mind for the exam.
PERCENTILES

The position of a user's score in his country as well as globally is returned in his profile as his

HOW IMPROVEMENTS ARE CALCULATED

As the user writes exams, his key criteria (scores, skill level and speed) are tracked and recorded in his profile. A graph is also provided for easy visualisation of the users trend.

The user's improvements are computed at intervals (daily, weekly and monthly) by comparing the user's score, skill level and speed in the current period (day, week or month) to the previous period (day, week and month). These improvements are returned as his/her 'daily improvement', 'weekly improvement' and 'monthly improvement'. Users improvements are strong criteria for the 'Halls-of-Fame'
