I was able to pass on my first try thanks to the meticulous lectures and systematic learning approach. I was at a loss as to how to study while working, but by repeating two or three problems every day, I naturally mastered the material. I believe it was possible because the curriculum was excellent. Thank you once again to the instructor!

While on parental leave, I decided to get the Big Data Analysis Certification and studied for about 2 to 3 hours a day for 7 weeks as soon as the written exam results came out. I am a non-major and had never written a single line of code before preparing for this certification. Because of that, there were many difficult parts while listening to the lectures, but I pushed through to the end anyway. Even after finishing the second review, I hit many roadblocks while solving problems and wondered if this was a certification I could actually achieve. Looking back now, I realize that feeling was perfectly natural since it was my first time. If you consistently stick to your daily goals, what you've studied will eventually become familiar to your eyes and hands, and you'll reach a point of rapid growth. While this course might not cover every single question on the exam, this isn't a test where you need to be perfect; it's an absolute evaluation where you just need to pass 60 points. Therefore, I believe trusting this course alone is more than enough. Thank you for the great lectures, the quick feedback on questions, and the tips provided right up until the day before the exam—they were very helpful. I think it would be even more beneficial for future students if a few of the lectures were updated to the latest versions. I wasn't even sure I would pass when I left the testing center, but I guess managing to solve and submit everything somehow helped, as I passed the 12th exam with a score of 75 and am now graduating from this course! I wish everyone preparing for the exam the best of luck, and I would like to thank the instructor once again!
