Yes, I agree with some of the reviews saying that Architecture and Application related questions are not valid or outdated. However, it is a really good preparation for the exam! oh btw, I passed the exam.

By Bengi Koseoglu on 6/17/2022

Overall it was ok and helpful, but not the best: (1) Too many spelling mistakes (2) Questions in test 1 and test 2 in python were very similar to each other (3) Some questions in technical side was very detailed for the exam (4) Question explanations were not clear enough

By Ravi Rai on 1/25/2022

Thank you Mert for such an amazing content. I have cleared the exam today. Keep up the good work !!! Also, Do you know of any course for Databrick Data Engineer Cert? Appreciate inputs/leads

By Andrew Sweeney on 7/30/2021

Questions are really relevant and even some questions came up almost literally in the real exam. The instructor is also pretty reactive and available to answer your question. It is a 5 stars course no doubt !!

By Igor Uchoa on 7/16/2021

That was a great test, but I think some questions contains errors and some alternatives was marked as right but not according to Spark Docs. I left some comments in the Q&A sections. I hope you guys could hit me back with the answers of them. THank you

By Pranshu Sharma on 6/6/2021

This course helped me with my preparation for Apache Spark Developer Certification with pyspark. The questions were concise and does prepare for actual certification scenario. I have passed the Databricks Apache Spark Developer Certification.Thanks!!

By Gokul on 5/30/2021

Pros: 1. Nice Attempt to check someone's Spark knowledge. 2. Covers all the key topics Cons: 1.Typo's could have been addressed 2. Could have executed the code block and provided the options accordingly 3. Question and options are irrelevant (very few only) 4. Redundant questions 5. could have added 3 more set of practice tests or price could have been better

By Navdeep Panwar on 4/8/2021

There are only 2 sample tests, which can be increased. But yeah, It helps me a lot to boost up my confidence to appear and crack the Databricks Certified Associate Developer for Apache Spark 3.0 exam. I got 87%, Thanks. Rating updated!!

By David Leee on 1/27/2021

good content but a little sloppy. some "correct" answers are wrong (for example include col("A") === col("B")), some questions have the same answer multiple times, and there are quite a few mispellings. still worth it for $13

By Martin Dubois on 1/12/2021

I have taken the exam once and failed. I feel like the questions are really similar, it's an excellent representation of the real exam. I highly recommend this course for anyone thinking to pass the certification.
