# Data Science Tests

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

**Data Science 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 Data Science 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

**Data Science Tests**. The details of each of these tests are as follows:

**"Data Science Practice Tests"**- In Data Science practice tests, there will be a series of practice tests wherein you can test your Data Science concepts on every chapter separately. There will not be any time limit on these tests. So, Data Science Practice Tests should be the first set of tests which you should attempt. Goto these practice tests

**here**.

**"Data Science Mock Tests"**- In Data Science mock tests, there will be a series of mock tests wherein you can test your Data Science concepts on every chapter separately, but there will be a fixed time limit per test. So, it is similar to Data Science Practice Tests, but with an added constraint of time limits. You should try Data Science Mock Tests if you are appearing for any online examination soon.

Before you get started on these series of online tests on Data Science, you should learn, study and practice our collection of 1000 MCQs (Multiple Choice Questions and Answers) on

**Data Science here**. We also prefer that you should practice Data Science practice tests and mock tests completely before attempting the certification test.

Here is the list of online practice tests and mock tests on Data Science. Each online test focuses on a

**"Specific chapter of Data Science"**. 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 Data Science. Data Science Certification test, Internship test, and Job Test are mentioned at the end of this list.
