What people say about Three-90 Challenge
Manish Kumar
"It’s an excellent program that keeps you engaged and motivated to complete the work on time. It’s particularly beneficial for those with limited budgets, offering great value. The motivation from the 90% refund makes it even better, and I received it quickly, which made the entire experience even more rewarding!₹4049 RefundedView All -->- Chaitanya Kumar Sinha"The refund deadline helps keep you punctual and on track. The videos are detailed and informative, but I wish there were more coding challenges in addition to the MCQs to further enhance the practical learning experience.₹5399 RefundedView All -->
- Ramdeep Kesharwani"An awesome journey full of innovation, enjoyment, and insightful knowledge. I loved every bit of it and would highly recommend everyone to go for it. The teaching styles of Ashish Jhangra Sir and Sampurn Sir were outstanding and engaging. I’m proud to have this course in my portfolio, and I can confidently say it’s the best course I’ve ever taken. Thank you, GeeksforGeeks and the entire team!₹4050 RefundedView All -->

It helped me gain a better understanding of the problem, develop an effective approach to tackle it, and apply logical reasoning to resolve it.
Reviews and Ratings
I have read all Placement Preparation Crash course tutorials and regularly practice problems according to the topics. I have also bought a Computer Science fundamentals course, which helps me understand the theoretical concepts of Computer Science.
I have taken Placement Preparation course and attended many web development-related courses. The structure of these courses is very well defined and has helped me secure a good job. While everyone in the market is selling their courses, only some are truly useful, and GFG ranks at the top of that list. Keep it up, team!.
Improved critical thinking and made me aware of the professional way of approaching a problem. Provides information on time and space complexity and the way of utilising those as per our needs.
The course gave me a complete structured path of learning and improving myself at my own pace. The best thing was that everything was there at one place. I didn't had to waste time in searching stuff and deviating myself from the topics. Its because of this course i landed a job with CTC of 20 LPA. :)
I recently completed the Placement Preparation course on GeeksforGeeks, and I must say it was instrumental in my preparation for technical interviews, eventually helping me secure a placement at Cognologix.
The course is well-structured and covers all the essential topics required to build a strong foundation in data structures and algorithms. The explanations are clear, concise, and supported by a plethora of examples and practice problems that solidify the concepts. The flexibility to learn at my own pace allowed me to thoroughly understand complex topics, revisit areas I found challenging, and practice extensively.
The coding practice problems and quizzes at the end of each module were particularly useful in reinforcing the learning material. Moreover, the discussion forums and detailed editorials provided invaluable insights whenever I encountered difficulties."
