掲示板 Forums - Verb/Adjective Changes/Conjugation Rules

Hello, I am having a hard time drilling the verb and adjective changes/conjugation rules (e.g. です、ます、 ichidan, godan and irregular verbs to present, past, formal, casual, negative etc.) into my mind. Obviously, I am still a lot confused. Could you suggest how I can practice this kind of grammar lessons? I am still at beginner N5 level and I think it'll be better to master the earlier rules before I proceed to N4. Your suggestions will be very much appreciated!

Thanks! I think i found it but I can't add it to my schedule when I clicked on the icon next to View.

Definetely looking forward later this year
