Making sure you study at the correct level is very important. Studying at the wrong level can lead to frustration if the course is too easy or too hard.
If this happens, you can change your level very easily with just a few clicks.
Just go to Course : Change Course and feel free to select the level that you think is more suited to you.
If you are unsure between 2 levels pick the easiest one and you can work your way up.
