How to continue from where I left of?

Once you login, click on your avatar in the header of the website, which will lead you to your profile Home page. You will find your recent lessons and uncompleted tasks listed there. Otherwise, you can click on the Course button in the menu to the left of the website, then click on the Quest you are currently on (it will have a ‘in progress’ button), which will lead you to the quest map (i.e. list of levels for that quest). You should then see the ‘in progress’ text next to the level your are on and Current Lesson icon to the right of the ‘in progress’ level.
