Hello @Sundar R​ , Yes I took the exam. Unfortunately I fail to reach the pass mark even though I got close. Things I could have did different:

1. I focused so much in mastering each topics i.e. linear, logistic & regularized regression, ALS and etc. But I could have understood every component without focusing on the mathematics behind the algorithm
2. It's not Technical exam so meaning you don't have to worry about coding or even backbone calculations of the algorithms
3. There is a lot of which of the following type of questions and case edged question i.e. you're the senior data scientist and your junior data scientist did this or asked you this.... kinda of questions
4. do not expect short questions that you think you'll save some minutes for the next questions (there are but don't plan on it)
5. There are long questions with long Multiple choices to read though so plan well with each questions.
6. it's a theory exam with experience backed answers.
7. in general it's relatively ease questions just be sure with your answers because they're closely similar.

Hope this will help you prepare for the exam. Am retaking the exam soon myself meanwhile i will try to share some resources that will help you.

Thanks.

Happy new year to you and everyone.💥
