I made a PDF with all conjugations for verbs, nouns and adjectives. You can find casual and polite forms there. The blue table is for casual u- and ru-verbs. In the first column you find the verb endings in dictionary form. Then just go to the desired column and see how the ending will change. If you print that document and use it for a few times, you will quickly remeber the the rules for conjugation.
But nevertheless I would encourage the Bunpro guys to give at least one example conjugation for u- and ru-verbs in the structure whenever a grammar point needs a specific verb-form. A structure like âverb[ă°] + ăăâ is not enough. I am always missing sample verbs there.
