In the Online Electrical Machines Test, for every correct answer, you will be given 2 points. There will also be negative marking of -1 for every wrong answer. So, you will have to be more careful in choosing the answers to the question in your online examination. If needed, you should skip to the next question and come back to the previous question later so that you can do proper time management for the online mock tests.
Based on your score, you would be given one of the following Grades:
Grade A* - Genius (You scored 100%)
Grade A - Excellent (Your score is in the range of 80% to 99%)
Grade B - Good (Your score is in the range of 60% to 80%)
Grade C - Average (Your score is in the range of 40% to 60%)
Grade D - Poor (Your score is in the range of 0% to 40%)
There will be 5 types of Electrical Machines Tests. The details of each of these tests are as follows:
For every "Electrical Machines Practice Test", Total Questions: 20, Total Time: Unlimited.
For every "Electrical Machines Mock Test", Total Questions: 20, Total Time: 20 Minutes.
For "Electrical Machines Certification Test", Total Questions: 50, Total Time: 1 hour.
For "Electrical Machines Internship Test", Total Questions: 50, Total Time: 1 hour.
For "Electrical Machines Job Test", Total Questions: 50, Total Time: 1 hour.
Before you get started on these series of online tests on Electrical Machines, you should learn, study and practice our collection of 1000 MCQs (Multiple Choice Questions and Answers) on Electrical Machines here. We also prefer that you should practice Electrical Machines practice tests and mock tests completely before attempting the certification test.
Here is the list of online practice tests and mock tests on Electrical Machines. Each online test focuses on a "Specific chapter of Electrical Machines". So, you should try both practice test and mock test on every chapter to do a self-assessment of your knowledge (along with time-limit constraints) in every area or sub-topic of Electrical Machines. Electrical Machines Certification test, Internship test, and Job Test are mentioned at the end of this list.
