I am a CompTIA A+ certified Remote Support technician.
The A+ is broken down into several parts
the 601 which is the essentials
the 602 which is for IT Technicians
the 603 which is for Remote Support Technician
the 604 Which is Depot Technician (like if you repair computers physically for your job)
You take the 601 and then one of the other 3. They are seperate tests, but you should study for both prior to taking the 601 - they have been know to throw questions that might be cross-over questions on the 601.
I took my training at a place called TechSkills, it is a mentored training, I would get the list of course work and hands on labs that i needed to do. I could do most of it from wherever I had a PC, and the labs were easier to do "on campus". All of my exams and stuff was computer based.
I took my Vendor Exam there too, it is done by Pearson VUE Each test was between 80 and 100 questions, all computer based... multiple choice.
My employer paid for my course and exam and books. I am thinking about going back for my 602 and 604
