• Similar to the first test, this test will be conducted in-class (HLSB 244) via Blueline.
• You are required to bring a laptop to take the test.
• The test must be taken using the Respondus LockDown browser. Be sure to have it installed and tested before the test.
• Also, plan to arrive early and make sure your wi-fi connection is working before the test begins.
• It is closed-book and closed-notes.

• factual knowledge: TRUE/FALSE, multiple choice
• conceptual understanding: short answer, discussion
• synthesis and application: describe/modify HTML page
  
  There is a practice test in BlueLine with examples of each type of question.
  Note: the practice test can only be taken using the LockDown browser.

• review PowerPoint slides
• reread book chapters and chapter summaries
• look over chapter exercises & projects, review questions
• if desired, reference other sources for examples & different perspectives
