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 !
