I have a question about some of the course material or course concepts. Can you help?

Most of the time you will be able to solve the query yourself, if not feel free to contact us.

• Yes absolutely.  Follow these steps carefully:
  • • Step 1: If you download a PDF version of the notes, you can use CTRL + F (or the Mac equivalent) to search for keywords that match your query.  You can review that along with the corresponding lecture.  In most cases, you'll find your answer there.
    • Step 2: Check our [KNOWLEDGE BASE] for free explainers on different key topics (there is a search function on the side or very bottom of the page).
    • Step 3: Check our [EXAM INFORMATION] archive (there is a search function on the side or very bottom of the page).
    • Step 4: Check our [STUDY TIPS] archive (there is a search function on the side or very bottom of the page)
    • Step 5: If you haven't found your answer using the 4 steps above, contact us for help.  We're available almost 16 hours a day, 7 days a week to assist.
