Which Level 1 course should I be taking?

I started Level 1 training a couple of weeks ago. At the time the ‘Level 1 - Foundation Training - 3’ course was listed at the top of the page. So I assumed that was the most up-to-date course. I am now in lessons 8 and 9 and am having a very hard time following the instructions for the practice exercises. I have noticed that ‘Level 1 - Foundation Training - revamped’ is now listed before the 2018.3 course. Which of these two courses should I be taking?
Are the instructions for the revamped course more up-to-date than the 2018.3 course?

Thanks in advance for any guidance


The new updated training is Foundation Training 2018.3

I am taking the 2018.3 training as its the latest when I sort it
