An Adaptive test can be defined as a stream of questions, each of which individually tests a student’s performance. He or she has to follow the proper order of questions, and cannot skip to the next one without answering the first one in place. This helps in ensuring that a student is completely prepared with all the topics, and has not concentrated on a few sections.
PlacementSeason is the only portal in this genre to provide online practice adaptive tests. Our adaptive tests adapt automatically to the ability level of the students attending the tests. For example, if an examinee performs well on an item of intermediate difficulty, they will then be presented with a more difficult question. Or, if they performed poorly, they would be presented with a simpler question.
Our practice Adaptive tests work in the following way:
- The student selects his or her desired level to be medium, medium-easy, or difficult
- According to the student’s correctness for first answer, our computerized adaptive tests adapt to the specific difficulty level.
- If answered correctly, the next question will be of higher difficulty. If answered wrong, the next question will be easier.
The following scenarios will further explain the use and need of our adaptive tests for students. Three students attend the same type of tests, with 20 questions each.
Scenario1:
- A student’s (‘x’) attempt for the first question is right, and he or she is awarded 1 mark for it. The next question will carry 2 marks. If it were answered wrong, the next question will also carry 1 mark.
- The same situation continues for alternate questions, with one attempt being correct and the other being wrong.
Hence ‘x’ answered 10 questions right, for which he/she was awarded 10 marks.

19 | 1 | Correct | 1 |
20 | 2 | Wrong | 0 |
Total Questions Correct – 10
Total Marks Scored – 10
Scenario2:
Another student ‘y’ attempts the test.
- The first answer was correct, so ‘y’ scores ‘1’ mark and moves to the next question.
- The weightage for the next question is 1 mark higher, giving it a weightage of ‘2’ marks.
- Hence each question in sequence carries a higher mark than the previous question if answered correctly.
- But ‘y’ answers wrongly from the 6th question until the 10th. The difficulty level and weightage reduces 1 mark per wrong attempt.
- The difficulty level from the 6th question goes down, with no marks being awarded. Again ‘y’ answers correctly from the 11th question until the 15th, leading to a gradual increase in difficulty.
- However, the decline in weightage repeats from the 16th to the 20th.

Scenario
- Here ‘z’ answers 10 questions successively right, with the weightage growing ‘1’ mark per question.
- Hence, ‘z’ scores very high, thous he or she answers the next 10 questions wrongly.

Conclusion: 10 questions were answered correctly by ‘x’, ‘y’ and ‘z’.
- In the first scenario, ‘x’ answered alternate questions correctly and scored the least. This is because the weightage reduced per wrong answer.
- In the second, ‘y’ answered alternate 5 questions correctly. The consistency of correct answers was partial. It was a result the swinging of difficulty levels and corresponding marks up and down.
- In the third, ‘z’ answered 10 successive questions correctly, with the difficulty level going up each time. After that, despite him/her answering wrongly, the marks remain the same. Hence ‘z’ scored the highest.
Hence the unique quality of our adaptive practice tests is that it promotes answering questions correctly in successive order. This analyzes a student’s proper knowledge in each level of the subject.
