<<The course is updated as per the skills measured on February 06, 2024>>.

WHY YOU SHOULD BUY MY PL300 COURSE?

a. 150+ deeply researched questions for PL 300. I create no more than three questions/day to maintain high-quality.

b. There are no simple one-liner questions. Each question is based on your understanding of a scenario. The questions challenge you to understand, apply, and analyze your knowledge.

c. I simulate the actual PL300 Microsoft exam experience for you in the form of drag-and-drop questions, dropdown questions, multiple yes/no questions with a radio button, repeated scenario questions, etc.

d. Clear and lucid explanations for both correct & incorrect answers.

e. Where required, each question comes with an attached PBIX file that you can download to verify your answers.

f. Supporting visuals created by me to drive better understanding (Not taken from Microsoft documentation)

g. Explanations run parallel to the product. Every detailed explanation has corroborating evidence with the Microsoft product (like Power BI Desktop or PBI service) shown in screenshots and clear callouts.

h. Explanations are NOT directly copied from Microsoft documentation. I have rephrased all the reasoning in a simple and easy-to-understand language.

i. No step-motherly treatment of incorrect answer choices. I took enough effort to explain the rationale for each answer choice (whether correct/wrong), including the reference links.

j. Don't worry about inaccurate sentence framing/wrong grammar/incorrect punctuations. I use Grammarly to review every question.

k. Almost non-existent repetition of questions only to increase the question count.

l. For some questions, you may have to search for answers in the given reference link. A Quick Preview feature shows a screenshot of the relevant paragraph to which the correct answer refers.

m. I love to help you succeed. If you need to discuss, we have an Active Q&A dashboard and expect fast responses (save for my sleeping hours, which are generally less).

n. As soon as there is an update from Microsoft, I try to update my course, keeping it always fresh.

o. The question bank is peer-reviewed every three months to ensure exam relevance.

p. Still not convinced? Check out sample questions on my YouTube channel/website before you decide to buy.

The questions are collected from a variety of domains and sub-domains with extra care taken to equal attention to each exam area. Also, the questions are on different levels.

For example:

1. Remember-level questions test whether you can recall memorized facts, & basic concepts.

2. Understand-level questions validate whether you can explain the meanings of terms, & concepts.

3. Application-level questions test whether you can perform tasks using facts, concepts, & techniques, and,

4. Analysis-level questions validate whether you can diagnose situations & solve problems with concepts & techniques.

A mixture of questions at different levels reinforces your knowledge and prepares you to ace the exam.
