Hi, this probably sounds like a stupid trick but for me I have a problem remembering the perfective and imperfective aspects of verbs if I simply read them...

e.g.

читать, прочитать

well obviously this one is very easy but it is just an example

so what I do if I see something like that is that I say in my head quickly:

Я читаю, Я прочитал

and I find it helps remembering them... especially because these are the forms I'm more likely to use. perfective in "past tense"

maybe this tip will help someone, although people on this forum (those who are not native Russian speakers) seem quite advanced and probably don't need this tip...

another tip is that I find for some reason watching English comedies dubbed to Russian helps... like that Mad About You TV sitcom.. or well, Russian comedies also help.

one Russian girl told me she learned English in Canada by watching the Simpsons (she moved when she was in her early teens). Probably an exaggeration since I didn't hear her saying "doh!" all the time
