I took the exam years ago when this wasnt a requirement. I looked online and it does appear you have to take it from home/work. The FAQs suggest that the "at home option" is less onerous than Oracle's at least:
You must work in a quiet environment with no other individuals present.
If your exam is 90 minutes or less, your workspace (desk) must be clear. If your exam exceeds 90 minutes, you may have food and beverage on your workspace, but it will be inspected by the remote proctor.
You may not have any other windows or documents open on your desktop.
If your exam is 90 minutes or less, breaks are not allowed. If your exam exceeds 90 minutes, you may take a break, but the exam clock keeps running.
Oracle requires you to be in a room with a door and such. That said, it would be a pain for me to get my apartment into a state that was acceptable for a Pivotal exam so not please about this direction.
I have a suggestion for you to clear this exam.
I highly recommend you to take this Spring Professional Certification course from Udemy https://www.udemy.com/course/spring-certified-tutorial/ These series of courses will be very helpful to pass the exam. I know three people passed the exam so far after they took these courses.
The instructor Dominik Cebula has finished module 1-4 and he is working on module 5-8.
However, these courses are for those who know the basics of Spring Framework and Spring Boot.
If you need some introduction courses for Spring, you may want to search Udemy.
I also recommend you to read Getting Started with Spring Framework cover Spring 5.
I had the Spring Core training by Pivotal last month. They have confirmed the exams are no longer taken at testing centers. If I am not mistaken you have to install some software on your laptop/PC and before the exam starts somebody will check the room via webcam. I also assume you are monitored throughout the exam. Basically you install a spyware on your machine
You need to go to examlocal.com to sign up for the exam. You need to click on the "Compatibility Tool" to check for system compatibility.
You have to install a Google Chrome extension as instructed. You will be being watched by a proctor.
I suggest you to reserve a study room in a public library for about 2 hours. Make sure there is no writing on the white boards in the study room.
You will share your computer screen with the proctor. The proctor will ask you to close other running applications on your computer.
The proctor will ask you to turn your webcam 360 degrees to make sure you don't have any notebooks, paper, notes on the wall, no electronic devices, no friends near you and etc.
Don't chew gum and don't move your mouth. The proctor just wants to make sure you are not communicating with anyone during the exam.
In my opinion, it is really helpful to take Dominik Cebula's training for only $10 (US dollar) / module. He will finish his module 5 - 8 by May 2020.
I passed this exam, but I am still taking his training courses. His courses are very helpful.
He is very passionate about Spring framework and Spring Boot.
You will learn a lot from him !
It's almost the same as it is with the Oracle certification you can take at home. Worse even, because they make you use Chrome . No matter how you look at it, it's still invasive and breaches privacy. After the Pivotal course I received a voucher to take the exam, but due to privacy issues, I probably won't take it. If I'll do take it however, then it will be at work in a meeting room on a "clean" computer.
