I recently completed a course on Operating Systems, DBMS, and Computer Networks, and I must say it was an incredible experience! The course covered all the important concepts in a detailed and easy-to-understand manner. The instructor was knowledgeable, approachable, and passionate about the subject, which made learning all the more enjoyable. The course content was well-structured and covered a range of topics, from the basics to the more advanced concepts. The assignments and assessments were challenging, but they helped me solidify my understanding of the material. What I appreciated most about the course was the emphasis on practical application. We had several hands-on projects, which allowed me to put what I had learned into practice. The feedback I received on these projects was constructive and helped me to improve my skills. Overall, I highly recommend this course to anyone interested in learning about Operating Systems, DBMS, and Computer Networks. Whether you are a beginner or an experienced professional, this course will provide you with valuable knowledge and skills that you can apply in your personal or professional life. Thank you to the instructor and the course creators for an excellent learning experience!

I would like to thank GeeksforGeeks from the bottom of my heart for providing me with a platform to learn. I was able to crack the interview of Infosys with the assistance of this course. Sandeep Jain's sir way of teaching is exemplary. He makes difficult topics easy to understand. He focuses more on building the basics which I think is very important for a better understanding.

I would like to thank, GfG for providing an amazing course covering all the CS fundamental subjects which are required to crack technical interviews. SDE Theory course helped me to build my concepts of core subjects like OS, DBMS, CN to get ready for the SDE job interview. Sandeep Jain sir has explained all the concepts in such a great manner that even a non-cs graduate having no prior knowledge of CS fundamentals subject can grasp it completely. I would like to thank Sandeep Jain sir for creating such an amazing course at such a minimal cost and also for making this amazing platform.

SDE theory courses have helped me a lot. I being an ECE student was not aware of core CS concepts and problem-solving techniques. The courses fulfilled all my requirements, and all the concepts were cleared very nicely from beginners to advance by Sandeep Sir and with video lectures that help me understand steps easily. It also has a theory which is the best part because when we read, we remember for a longer period of time.
