こんにちは！
I’ve just started learning Japanese, and currently just finished learning Hiragana and Katakana. I watched [this video](https://www.youtube.com/watch?v=L1NQoQivkIY&list=LL&index=14&t=138s) and have bought [Genki 1](https://www.amazon.com/Genki-Third-Integrated-Elementary-Japanese/dp/4889969446/ref=sr_1_2?crid=31SJE0UROANM9&keywords=genki+1&qid=1666970650&qu=eyJxc2MiOiIzLjE1IiwicXNhIjoiMi42NCIsInFzcCI6IjIuNDUifQ%3D%3D&sprefix=genki+1%2Caps%2C137&sr=8-2&ufe=app_do%3Aamzn1.fos.006c50ae-5d4c-4777-9bc0-4513d670b6bc) for grammar and [Tango N5, N4](https://www.amazon.com/Nihongo-Vocabulary-Practice-Questions-Hiragana/dp/B08WRCPS3S/ref=sr_1_2?crid=GPLH4RTE06PT&keywords=tango+n5&qid=1666970683&qu=eyJxc2MiOiIwLjk5IiwicXNhIjoiMC41NyIsInFzcCI6IjAuNTkifQ%3D%3D&sprefix=tango+n5%2Caps%2C106&sr=8-2&ufe=app_do%3Aamzn1.fos.f5122f16-c3e8-4386-bf32-63e904010ad0) for vocabulary. I plan on getting Remembering the Kanji for Kanji, as well.
My question is, should I be doing these together, or would you recommend I start with one before moving on to the other? To be honest it feels a little overwhelming, albeit I’d expect that when starting a new language!
