Grade =
Correct answers are:

  1. you don't need to spend $1,000+ on boot camps or courses to pass the CompTIA tests.

  2. neither is it necessary for you to spend a YEAR in classes at a college or tech center (although Omega recommends you take at least one advanced course after studying on your own to answer those lingering questions. The course curriculum should include a lab where you can get "hands on" experience assembling and disassembling computers and printers)

"Some additional test taking Strategies"
  1. Quickly scan the question for key words and the main idea.
    Determine what the question is about in general. Don't get bogged down in details. Many questions add extraneous technical material designed to confuse you.

  2. Now reread the question more slowly and carefully. Especially the last sentence or two to find out what the question is asking you for. Try to make associations between the key words in the question and key words in the answers. Eliminate any answers you know are wrong.

  3. Now link the question to the best answer.
