Our Digital Communications Tests allow you to experience an online examination in the real-time environment. In every online test on Digital Communications, you will be presented with Multiple Choice Questions (MCQs) which will test your skills in Digital Communications Concepts in a detailed and comprehensive manner. In the test, each question will have 4 options to choose from. You should select only 1 correct option as an answer and then move on to the next question. Once you submit answers to all the questions, you will be given your final test score.In the Online Digital Communications 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 Digital Communications Tests. The details of each of these tests are as follows:
1. "Digital Communications Practice Tests 1-10" - In Digital Communications practice tests, there will be a series of practice tests wherein you can test your Digital Communications concepts on every chapter separately. There are totally 10 different chapters on this subject and hence there will be 10 different practice tests wherein each practice tests covers one chapter exclusively. There will not be any time limit on these tests. So, Digital Communications Practice Tests should be the first set of tests which you should attempt. Goto these practice tests here.
2. "Digital Communications Mock Tests 1-10" - In Digital Communications mock tests, there will be a series of mock tests wherein you can test your Digital Communications concepts on every chapter separately, but there will be a fixed time limit per mock test. Here also, there are 10 mock tests wherein each mock test covers only one chapter exclusively. So, it is similar to Digital Communications Practice Tests, but with an added constraint of time limits. You should try Digital Communications Mock Tests if you are appearing for any online examination soon. Goto these mock tests here.
3. "Digital Communications Certification Test" - Once you are thorough with your Digital Communications concepts, then you can try our Digital Communications Certification Test wherein your name will be mentioned in Top Rankers list, if you scored either Grade A* or Grade A in the Digital Communications Certification Test. The Certification Test is free. Goto Digital Communications Certification test here.
