Virtual learning is a new idea that has attained a new form with the emergence of new technologies such as the Internet. One of the issues in the field of E-learning is the way of announcing exams? grades. In this paper, a new method is introduced for restricting public access to exams? grades on the web by using a new HIP (Human Interactive Proofs) system. In this method, the picture of a multiple-choice or short answer question from the exam is shown and the students are asked to answer it for accessing the grades. Since the picture of the question is viewed the computer cannot answer it. On the other hand, only students of that course can answer the question and have access to grades because of the professional nature of the question. This project has been implemented by PHP scripting language.
