Transliteration and alternative options
First of all, transliteration isn't quite what I expected, I've been learning Russian for a while and I came here for a quick refresh on some things and what seems to be bugging me are the lack of alternatives for translations or a single typo and the whole answer is wrong. Transliteration is bugging me because it is not approaching the real pronunciation of the word, and the alphabet is very vaguely explained, not a single record of a word that contains the letter or anything. Also there should be like a word checker when typing phrases to check how many common words are compared to the right answer and thus tell how wrong or right we are.
After a lesson is started, there will be a little Aa switch on the upper left. Click on it, it will turn to Яя, and the Cyrillic alphabet will be used. Should the switch be reset at some point, which occasionally happens, just set it back to Cyrillic. Get past the awkward transliteration and things should improve for you.
It is somewhat irksome when Duo does not accept a translation. You can report what you think is a problem with a question/answer/translaton by using the button provided at the bottom of a page, and your suggestion may be accepted in time.
Also, since you are reviewing, you may want to try English for Russian speakers, too, which will provide more translation into Riussian. It has its translation quirks, too, but they are not difficult to get used to. Definitely subscribe to the forum for this course and for any of the other "for Russian speakers" courses, as the discusions are in Russian, and they provide great reading practice in colloquial Russian.
And if there is a "Погружение" button on your Duolingo dashboard at the top of the page, try that, for translating articles into Russian.
Are you seeing exercises in the Latin alphabet like this text, or in the Cyrillic alphabet like: "Галина Николаевна Симонова-Щепетнова" (name of an actress I happened to be discussing earlier and so had in my clipboard, because I don't have a Cyrillic keyboard on this computer)?
I'm not sure if I understand you correctly, but you're complaining about transliteration and from other sentence discussion posts it sounds like you may not have the Russian course set to use Cyrillic. There should be a switch in the upper left once you start a lesson (beside "Tips & Notes") that will let you switch.
I've heard (and possibly experienced) that some exercises do not accept transliterations very well, plus Russian is generally written in its own Cyrillic alphabet rather than transliteration, so you may do better with the actual Cyrillic. You will need to install some sort of Russian keyboard on your device to use the Cyrillic lessons; see here: https://www.duolingo.com/comment/11449014
