Reinforcing -er -ar -or endings?

Duolingo is fantastic for expanding your vocabulary and learning the rules of the language, but I'm having some confusion with the endings (especially when it's left up to the voice interpreter where it's often very difficult to distinguish between -a- -e- and -o-). For example, I almost always type "lager mat" when "lagar mat" is correct, but duolingo gives me a pass because it's very close to correct. I'm not saying that I want to be penalized for those kinds of mistakes, but I would like a better way of reinforcing the correct ending. Does anyone have any good methods that they have used that would be helpful?

My best tip is to learn the regular verb groups and how the past participle, supine and preterite are formed. The three big regular groups are verbs ending in -er and ar, plus the short stem verbs. Then you will hopefully see the bigger picture and have more of a system to understand the verb conjugations in. A tip is to learn the imperative: if it ends in -a, then the conjugation is that of a regular -ar verb. Wikipedia has quite good page on it:
