First off, don’t be pressured to finish this as fast as you can. Like other people mentioned, take around 50 (depending on you less or more) a day and finish it slowly. If you know that you are going to continue and you are going to stay committed. I suggest going on the all levels and just reviewing the kanji. You could also take the reviews depending on the levels.

You got this! Don’t feel stressed and you’ll be done with it in no time.
Good luck!
