Есть тест, который немного не правильно подсчитывает баллы. Создал тест, в нем два вопроса. В каждом вопросе по 4 вариантов ответа, и в каждом один правильный ответ. Если выбрать в одном вопросе правильный ответ, а в другом один не правильный, то результат 75 баллов.. Если выбрать в одном вопросе правильный ответ, а в другом два неправильных ответа, то результат 50 баллов. Ну соответственно при выборе правильных ответов в одном и другом вопросе результат 100 баллов.
Вопрос в том, что почему, если выбрать в одном вопросе правильный ответ, а в другом один не правильный, то результат 75 баллов?
