How do I schedule to take these exams? Network+, Server+ and Security+

Rebsat

How are you doing everyone? I am working as an IT Technician in a company. I have a bachelor in computer science but I have not taken any IT Training courses in my life yet. I would like to take these exams and my question is...
Do I have to take each exam immediately after finishing it's training course? I do mean Is it possible to postpone the exam of the training course I would like to take (Network+) and going for taking another training course (Server+) instead? and whenever I finished the training course of (Server+) then I would go to take the exams of (Network+) and (Server+) one by one.
Thank you very much for your good answer.

Some classes, you can take the exam right after. However, it is how you feel if you think you can.
