I recommend using Genki for your primary study and Tae Kim for supplemental study. Genki gives more straightforward, easy to understand explanations for grammar points, and it has a ton of exercises in the textbook and the workbook, and the listening portion is great too. Tae Kim is good for some things, but for some grammar points I feel he doesn’t offer much explanation. You could also check out imabi for supplemental study, it’s a free online resource that goes into great depth with grammar points. It’s a bit intense to use as a stand alone study, but if you want extra clarification, it’s great for that.
As for reading them, this is how I study with Genki:
- First, check out what vocab is coming up in the chapter and add any unknown vocab to Anki. If it’s vocab that uses kanji I haven’t learned yet in wanikani, I learn it in hiragana rather than teach myself a bunch of new kanji before they show up in WK.
- Go through the grammar points, taking notes in a word document and copying down example sentences into another word document and adding some to anki to practice.
- Once I’m done with that, I go through all the textbook exercises. For the ones with a listening component, I use that. I also do all the exercises in the workbook. It takes more time to do all the textbook and workbook exercises, but I come out feeling much more confident with the grammar points having done that.
- Once I’m finished with the chapter, I read the dialogue at the beginning of the chapter. I then listen to it without looking at the text and try to understand what’s being said. I usually repeat this until I can understand it fully without looking at the text. Genki’s listening exercises might not seem helpful with understanding real spoken Japanese, but it helps you get started with it, and it helps you understand what words and sentence patterns sound like.
When I don’t understand a point or I need more clarification, I usually search it in Tae Kim’s guide first. If I don’t find anything helpful there, I check Imabi. If I’m still confused, I’ll watch a Japanese Ammo with Misa video on it.
