Но садистские наклонности Сорокиной Екатерины Александровны просыпаются во время защиты дипломных работ!
Она не по-наслышке знает, как защита важна и ДОРОГА для студентов.
Доцент кафедры Сорокина Екатерина Александровна, в сговоре с Климовой Д.В., заведующим кафедрой – В.А. Аксеновым, не то что поимеют последние деньги со студентов, но и душу!
Бесконечные придирки по оформлению работ говоряшие о возрастании цены защиты!
Ввиду своей личной несостоятельности, Сорокина Екатерина Александровна особое внимание уделяет своим одногодкам. С особенным рвением относится к будущим мамам.

Its like you read my mind! You appear to know a lot about this,
like you wrote the book in it or something. I
think that you could do with a few pics to drive the message home a
little bit, but other than that, this is magnificent blog.
A fantastic read. I will certainly be back.

your post’s to be just what I’m looking for. Would you offer guest writers to
write content for you? I wouldn’t mind writing a post or
elaborating on some of the subjects you write in relation to here.
Again, awesome weblog!
