Our review

--- **Overview:** The Global course rating stands at 4.38, with all recent reviews pointing towards a comprehensive yet improvement-oriented learning experience. The majority of the feedback praises the content for its thoroughness and practical application, particularly in the field of RHEL 8 system administration. However, several recommendations have been made to enhance the course's delivery, clarity, and accessibility. **Pros:** - **Content Completeness:** The course covers a wide range of topics and provides ample examples for practical application, which is highly appreciated by learners. - **Expertise:** Sikhar, the instructor, is commended for his deep knowledge in the field of Linux and system engineering, with many learners finding his detailed explanations very helpful. - **Real-world Application:** Learners report that the skills they have acquired through this course are directly applicable in industrial scenarios, making it a valuable resource for professionals. - **Interactive Learning:** Some learners express the desire for more interactive sections within the lectures where they could ask questions, which could be an opportunity to enhance engagement and comprehension. - **Variety of Resources:** The suggestion to include additional resources such as PDF tutorials with screen shots would greatly assist learners in implementing the course content effectively. **Cons:** - **Video Clarity:** Some learners have found the videos' screen resolution and the clarity of the instructor's speech to be lacking, which could impede understanding. - **Language and Presentation:** The instructor is noted for using filler words like "you know" frequently, and there is a call for a more professional approach to language and presentation. - **Pacing and Delivery:** The pacing of the lectures is reported to be fast, with commands being spoken and displayed quickly, which might result in learners missing important details. This also includes the occasional mix-up of terms due to a thick accent. - **Structured Approach:** A significant number of reviews highlight the need for a more structured approach during lectures and labs, especially for beginners who find it difficult to follow without proper guidance. - **Subtitles Accuracy:** There are mentions of inaccuracies in subtitles, which could mislead learners if not reviewed and corrected. - **Lab Guides:** The absence of lab guides or structured lab approaches is seen as a gap, with some learners expressing that the course seems to be tailored for experts rather than beginners. - **Quiz Questions Relevance:** Some learners suggest that quiz questions were not always covered in the lectures, which could lead to confusion and a lack of comprehensive preparation for assessments. **Recommendations for Improvement:** - **Improve Video Quality:** Enhance video resolution and clarity to ensure learners can see and understand all screen content. - **Professionalize Language:** Encourage the instructor to use a more professional language style and to eliminate unnecessary filler words. - **Slow Down Pacing:** Adjust the pacing of lectures to allow learners to better keep up with commands and explanations. - **Provide Structured Labs:** Introduce guided labs with clear instructions to help beginners follow along more easily. - **Verify Subtitles:** Ensure that all subtitles are accurate and reflect the instructor's words correctly. - **Review and Add Quiz Questions:** Align quiz questions more closely with lecture content to ensure learners are tested on material they have covered. - **Offer Additional Resources:** Provide supplementary materials such as PDF tutorials to complement the video lectures, enhancing the learning experience for all levels of proficiency. **Conclusion:** The course is highly valued for its comprehensive coverage of RHEL 8 system administration topics and the expertise of the instructor. However, to improve learner satisfaction and effectiveness, it would be beneficial to address the issues related to video clarity, language, pacing, and the provision of additional learning resources. With these enhancements, the course has the potential to become an even more powerful tool for professionals seeking to advance their skills in Linux system administration.
