Question about Cloudera Data Engineering Certificate CDP-3002

I'm going to take a Cloudera Certificate Exam (CDP Data Engineer Exam CDP-3002). I have already read the FAQ section, but I still have some questions about it. Please understand that I'm just a fresh graduate student from a 3rd world country, so the 333$ cost is very high for me. So I need to make sure I am fully prepared before paying for the exam.

1. From payment, how long does it take until I receive an email with detailed information about the test?
2. From payment, how long does it take until the test starts?
3. The email will guide me in detail on the steps to start the exam, right?
4. I read through the FAQ section, is there a person called "proctor" who will instruct me on what to do before the exam?
5. I just need to install the Questionmark Secure software, right?

6. There are only multiplier choice questions and no exercise questions (I have to code), right?

 

Sorry for all the questions, please understand for me because I'm very confused right now. There isn't much thing on the internet about this certificate exam.
