In school, 11 words-exceptions were forced to teach, even the mnemonic rule was given:
Push, hold, look and see,
To hear, to hear, to hate,
to turn, and to turn,
To suffer and to suffer,
You will remember, friends,
You can’t put them on “E”.

But is there still to run, rush, whistle, scream, feed, whistle, knock, whistle, and so on?

How did you get into a society of sceptics?

About the fact that in 11 exceptions, the voices in the suffixes when spinning happen to be unsuccessful, and you need to indicate somehow that there is not 'e' and ' and' in school you have not been told yet?
And in those you have listed, it is difficult to write wrong, because the voice in the suffix is always under emphasis. If, of course, the Russian language is your native.
