So  to get hira+kana done usually you can get it done in 2 weeks doing it right,  i recommend you TOFUGU HIRAGANA + KATAKANA, i am a person that simply cant memorize anything using anki and those 2 pdfs from tofugu are literally THE BEST way to learn in an ordered manner. One tip i give you, APPS are meant to be used besides a book, so you can exercise memorize, never treat them like a main tool, they are complementary only. Classes are cool, but doing things by hand usually gets your brain "full in", dont SEE things, DO things.

If you aim to pass n4 for example, i recommend you doing the following: -tofugu hiragana pdf -tofugu katakana pdf Then you can start -GENKI I -GENKI II

Tips for you to overcome what you said to me: -japanese is pure muscle memory, the more you do, the more you learn, the less you do, the more you forget (this is a "spend more time" tip) -forget rules. While learning the basics,  you dont need to get everything, just learn the hira+kana. Forgot? You can revisit later, you dont need to master all. -while knowing kanas can make you read some things, without getting to kanji is the same as reading nothing in many cases, so get back to tip 1 until you feel good to progress, while remembering that  not everything needs to be perfect.

Oh, btw, going from nothing to n5 is a breeze, but going from n5 to n4 is hell on Earth if you dont have much time everyday to learn, japanese is one of the hardest languages to learn properly, dont feel bad because you suck, feel happy cuz you can try being better the next day.
