Hi @linuxpython The exam that the previous course was based on is no longer available. The 2018 version of the course is based on the new exam. Many of the concepts are similar and you may not have to start over completely. Depending on how long your break was, you might want to start over anyway just to make sure you haven't forgotten too much. If you are short on time, consider watching the videos on the topics you are most comfortable with at a faster playback speed. I know several people have done that and felt that it was effective. It might work for you as well.
