This paper explains about a new and comprehensive Internet site which the author and colleagues Katsumi Iwasaki and Keiroh Maeda are constructing. The site, supported by the Japanese Ministry of Education, will feature thousands of realistic TOEIC and TOEFL exercises that anyone can access from the Web. For no fee, students will be able to prepare for two of the most important tests in the world of English language education today. The site will be unique because it will take into account Japanese students' English language strengths and weaknesses. The first half of this paper explains about the tests, and about how the Internet site will be constructed. The second half of the paper explains about a series of practice tests which were given to Japanese university students in an attempt to assess their English language abilities. With respect to student abilities, for example, it was found that most of the university students in this study do not have good control of the following vocabulary expressions: to initial, to grin from ear to ear, price dropped, and in the long run. In listening, students have a hard time understanding when a speaker says "no" in an indirect way. In reading, it was found that restatements can be tricky. The results of the tests will be used to make high-quality TOEIC and TOEFL questions in the near future.
