Seven years ago, the system of the joint first-stage achievement test was newly introduced in order to improve the status quo of the entrance examination for the national university candidates. From the outset, naturally, various problems have been pointed out, discussed by the experts of various fields concerned, and it was decided to make some necessary amendments from the academic year 1987. Decisive means, however, to solve the problem definitely, has not been found out yet. The author, in process of the analysis on the data of the 1st year achievement of the pioneer students (entered in 1980) of our newly founded university, noticed quite incidentally that one of the main causes to get into various troubles consists in the so-called self-estimation system. This article, accordingly, reports the process how the clue was found, demonstrates the extent how much the self-estimation system badly affects the probable occurence of fluke, and finally proposes the abolition of this self-estimation system, in order to continue the present system of the joint first-stage achievement test, and, to achieve one of the original objectives : to avoid the so-called a single shot match.
