Светлана Доброго времени суток, Светлана! Хочу поблагодарить Вас. Я вчера сдала работу после вашего сопровождения и защитила ее на отлично!!! Не могу сказать, что преподаватель был в восторге, но изучал работу очень заинтересованно и в итоге не нашел ничего, к чему можно было бы придраться. Мое мнение о работе исключительно положительное. Если честно впервые внимательно прочитала ее за 3 часа до сдачи, но меня поразило насколько легко, последовательно и логично был представлен материал, за счет чего я смогла за 2 часа изучить работу настолько, что была на 99% уверена в знании любого вопроса в рамках материала курсовой работы. Кроме того, могу отметить очень органическую связь между теоретическим материалом и практикой, проще говоря, знакомясь с практической частью у меня не возникало вопросов, типа как обосновать или на основании чего было сделано то или иное утверждение. Еще раз благодарю Вас и надеюсь на не менее плодотворное сотрудничество в будущем!!! С уважением, Светлана
