I had the same issue when I started out, but now I'm just going with the order on the website. I also find that the skill level required jumps around, but stick with it! It's probably common to not understand dialogue the 1st time through, so try to hang in there and listen to it a couple times to let it glue in your head a little better. Take a look at the dialogues and see if it feels right for you too. Good luck and 加油！
