If you opt for the Expert version of your course, the time you have to interact with your tutor is limited to course length. You will have one week per lesson to chat to your tutor and to have your assignments marked, and during this period you can ask them as many questions as you would like. To find out the length of each course, head to the product page and look at the Course outline to see how many lessons it contains. e.g. a four lesson course assumes that you will have completed the assignments within four weeks. Your tutor interaction period will start as soon as you enter the classroom. If you find that you are struggling to complete the assignments in the allocated time or you wish to put this function on hold, just get in contact with one of the team via the support button and we will help you out.
