If I schedule it for December, do you think 3-4 months is enough time to study for it being a novice? I know it's a really difficult exam but I am prepared to study daily. Please let me know your experience with it. Thank you.
3-4 months daily study should be good enough. But it is necessary or very helpful to take Qlik self learning from Qlik Learning: Continuous Classroom or in class training. Then more hands on practice.
You can also do self assessment to see if you are ready. Take the Qlik Skills Assessment: Become A Qlik Power User
Best luck
