Course Content & Structure

Pros:

• The course content is generally good, providing a solid foundation on the subject matter.
• Some instructors offer insights into how concepts are applied, which can enhance understanding.
• Resources like Tutorialspoint are referenced, suggesting additional learning materials.

Cons:

• The instructor's delivery is a major drawback, with several reviewers mentioning that the instructor reads from slides too quickly and with a heavy accent, which can make it difficult to follow along.
• The pace at which the instructor moves through diagrams and content is fast, potentially leaving learners behind.
• Some users found the course material "dreadful" to understand due to the presenter's unclear speech and lack of engaging examples or explanations.
• The course's language barriers, with some viewers finding it more effective to mute and read the slides themselves.
• A significant number of reviewers expressed dissatisfaction with the instructor's approach, describing it as a "waste of money" because it lacks natural explanation and additional information on topics.
• Pronunciation errors, specifically regarding the acronym DL/I, which stands for Data Language/One, not "Data Base/One."
• A strong negative reaction from some users who found the course to be on par with a "STUPID VIDEO EVEN A KID CAN READ BY SEEING," accusing the instructor of being a "blady cheater" and urging Udemy not to promote such content.

Delivery & Presentation

Pros:

• The course's structure is outlined in a way that provides a clear path through the material, which some users find helpful as an introduction to the topic.

Cons:

• The presentation suffers from a lack of clarity due to the instructor's reading style and monotone voice, making it hard for learners to maintain focus.
• The instructor's English is not clear, which impacts the overall comprehensibility of the course.
• The format of the course could be improved by presenting content in smaller segments with individual narratives, offering natural pauses and a more engaging learning experience.

Final Verdict:

The course has its merits in terms of content but falls short in delivery and engagement. To improve the learner's experience, it is recommended to consider re-recording the course with an instructor who can articulate concepts more clearly, provide engaging examples, and deliver the material with better pronunciation and a more natural speaking style. Additionally, breaking down the content into smaller, more digestible segments could greatly enhance the learning experience.
