The OA of module D427 consists of questions that will require you to write down SQL scripts as answers. So the Lab portion of the Zybook holds significant weight in the overall content of the module. Make sure to practice these labs as many times as possible to understand the scripting process and get familiar with the code and the many errors that you might come across. We also highly recommend that you take short notes on all the significant sections that we have outlined above and make your flashcards to help you study the material. Successfully completing the Zybook and understanding the material 100% will be the main tool that you require to pass the OA on your first attempt.
Week 3 – Watch supplementary videos
When you are going through the Zybook, you might come across many concepts that you might find hard to grasp in a Textbook format. As with all programming modules, visual learning will always be a better learning method to see someone else explain the scripts while they write them down. So whenever you feel stuck, or you are not able to understand a concept in the Zybook, Always refer to the internet to find a number of resources that can clarify your doubts in many different ways. To help you with this task we have listed several important external study resources in the “External Resources” section of this article. Also, you can navigate to the location mentioned below to find several supplementary videos provided to you by WGU to help you clear your doubts about the course content.

Week 4 – Practice your knowledge
Once you have completed your studies on the Zybook, you will have equipped yourself with the necessary knowledge to pass the OA of D427. So let us test your knowledge and your memorization skills by attempting a practice test. Open the link provided below and attempt to answer each question to refresh your memory on the key concepts of this module.
Practice test – Link
The main objective of this practice test is to refresh your knowledge of the key concepts you have learned. So feel free to refer to your short notes if you require assistance to answer any questions in the test. Go through the test from beginning to end to validate your knowledge before moving on to the next step.
Week 5 – Evaluate your knowledge
As the final tool to practice our skills on the knowledge, we will utilize the Pre-A of D427. The Pre-A is a valuable tool that can provide you with an accurate report on your knowledge and showcase the weak points that you need to improve on before attempting the OA. As this is a mock exam, the Pre-A will simulate the OA as closely as possible to provide you with a real exam environment. So it is necessary for you to attempt the Pre-A with the same mindset and treat it as a real exam. By doing so, you will get to realize your weaknesses in both your knowledge as well as your exam-taking skills with this tool. Once you are fully prepared, go through the Pre-A and complete it.
Once you complete the Pre-A, you will receive an auto-generated coaching report based on your performance in the Pre-A. This report will show you your competency in each chapter of the module. Use this report to identify the chapters where you have scored the lowest and revisit these chapters using your short notes to clear the doubts in your knowledge. Once you have cleared your doubts, retake the Pre-A and try to achieve a score of more than 85%. If you fail to achieve this score, rinse and repeat the same steps until you are able to score above 85% before moving to the next step.
Week 6 – Sit for the OA
Now you have arrived at the final step of our ultimate study guide. By following the above steps, you are now fully prepared to face the final challenge head-on and achieve success in module D427. So without hesitation,
- Schedule the OA at a convenient time and date for you
- Make sure you have a stable internet connection, a webcam, and a microphone.
- Follow the proctoring instructions and rules carefully.
- Use the same strategies and skills that you used for the Pre-A
- Relax and be confident in your abilities.
- Face the OA with all you’ve got.

Tips to prepare for the OA🎯
Preparing for the final assessment in the Data Management – Applications module requires strategic planning and focused study. Here are some tips and tricks to help you manage your time effectively and tackle both the multiple-choice questions (MCQs) and SQL statement writing questions. First, ensure you thoroughly review sections 1, 2, and 4 of the course materials, as well as all the labs. These areas are crucial for understanding the core concepts and practical applications of SQL. The Objective Assessment (OA) is closely related to the chapter participation, challenge activities, and labs, so prioritizing these will give you a solid foundation.
To manage your time efficiently, start by creating a study schedule that allocates time for each section, with extra time for chapters 7 and 8, as they are particularly important. Practice writing SQL statements frequently, as this will help you become more comfortable with syntax and query structure. Focus on understanding joins, including right joins and referencing tables accurately. Make sure you know how to add primary and foreign keys in CREATE TABLE statements, as well as how to identify these keys in multiple-choice questions. Being able to distinguish between Data Definition Language (DDL) and Data Manipulation Language (DML) statements will also aid in answering syntax-related questions.
During the assessment, carefully read each question to determine whether it pertains to DDL or DML. Familiarize yourself with CREATE, UPDATE, ALTER TABLE, CREATE VIEW, and CREATE INDEX statements. Be prepared to use INSERT INTO statements and understand aggregate functions like COUNT, MAX, and MIN. Additionally, practice GROUP BY and ORDER BY clauses, as these are commonly tested. When faced with MCQs, use the process of elimination to narrow down your choices, and for script-writing questions, double-check your syntax for accuracy. Remember, the passing score is 70%, so aim to be confident in at least 70% of the content. With these tips and a focused study plan, you’ll be well-prepared to succeed in your final assessment.
