beta.. see.. while reading a fiction novel, you will almost never understand 100% of the things, so it's ok and acceptable if you are encountering a couple of new words every page but are still able to understand the scene and the story, but if you are really encountering a new word after every 2 lines, then in that case, the book is a little above your level and you should put it down.
Word lists never help and no book ever requires you to cram a list of words before you begin reading it. So, no need to work with that list or any such list ever. It will be a humungous wastage of your time. Move to a lighter book and do not increase the difficulty level for 3-4 books; after that, you can increase the level. Hopefully, you won't face any issue then.
