That would be awesome for Russian course!! I grew up with 2 mother languages (Spanish and English). I feel bad for English speakers when they are trying to understand the concept of "gender word combinations" in a language like Spanish :(
If there is "а" in the and it is almost always feminine. Some exceptions are "папа" (French word). Anyway use other sources like https://ru.wiktionary.org/wiki/%D0%B2%D0%BE%D0%B4%D0%B0
"Мой is the masculine pronoun used with masculine nouns as in "мой нож" (my knife)
Моя is the feminine pronoun used with feminine nouns as in "моя вилка" (my fork)
Моё is the neuter pronoun used with neuter nouns as in "моё окно" (my window)
It's important to note that here the gender of the pronoun is determined by the gender of the noun, not by the gender of the speaker
The plural first person singular possessive pronoun is мои and it is the same for all genders."
I got this from the link above.
