**Digital Circuits Tests**allow you to experience an online examination in the real-time environment. In every online test on Digital Circuits, you will be presented with Multiple Choice Questions (MCQs) which will test your skills in

**Digital Circuits 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 Circuits 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 Circuits Tests**. The details of each of these tests are as follows:

**"Digital Circuits Practice Tests 1-10"**- In Digital Circuits practice tests, there will be a series of practice tests wherein you can test your Digital Circuits 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 Circuits Practice Tests should be the first set of tests which you should attempt. Goto these practice tests

**here**.

**"Digital Circuits Mock Tests 1-10"**- In Digital Circuits mock tests, there will be a series of mock tests wherein you can test your Digital Circuits 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 Circuits Practice Tests, but with an added constraint of time limits. You should try Digital Circuits Mock Tests if you are appearing for any online examination soon. Goto these mock tests
