The self-study exams are in January, April, and October, three times a year.
The data analyst is allowed to take the exam four times a year, and then the dates are March, June, September, and December.
Then there is only one chance to apply for a deferral, and if you have to pay another 90 bucks for a make-up exam.
You can talk to your teacher to get information about the subjects of the exam, to facilitate the preparation of the exam, I wish you good luck with the exam ah.
