Hello, I'm doing the azure fundamentals AZ900 course through IBM (GTS L&K EMEA - portal). While doing the course I activated the sandbox for doing the exercise which is in part 2 module of the course (SQL database). After following all the steps just before I proceed with the "review+create". It's showing me the monthly charges as "$380". Isn't sandbox free? Or it's just showing and I won't actually be charged? I was very confused if I should be proceeding further or not. So right now I'm stuck at here in the course can't go further without completing the exercise. I have also attached the Picture of what it looks like. Please help me with this. Thank you.
