How to Think Like a Technician
The A+ exam rewards understanding rather than memorization. Start by identifying symptoms,
forming a theory, testing that theory, creating a plan, implementing the fix, verifying full functionality,
and documenting your work. When you answer exam questions, eliminate obviously wrong choices
before selecting the best answer.
