DCFirst Claim
1. An educational system for assessing a student'"'"'s understanding in a subject, the system, using latest test results from the latest test taken by the student and the prior-to-the-latest test results, comprising:
- a score generator for accessing the student'"'"'s prior-to-the-latest test results and the latest test results; and
a recommendation generator coupled to the score generator for;
accessing a set of analysis rules, with a plurality of the rules being subject-specific; and
analyzing the student'"'"'s prior-to-the-latest and the latest test results using the set of rules to generate a recommendation, which provides an assessment on the student'"'"'s understanding in the subject.

Abstract
An educational method and system that assess and enhance a student'"'"'s understanding in a subject. Based on the student'"'"'s understanding, individually-tailored tests are generated, whose difficulties are geared towards the student'"'"'s level of understanding in the subject. Thus, the student not only can use the tests to prepare for an examination, but can also use the tests to learn the subject. The system includes a score generator coupled to a recommendation generator. In one preferred embodiment, the recommendation generator includes an inference engine, and in another preferred embodiment, the recommendation generator includes a pre-requisite analyzer. Both the pre-requisite analyzer and the inference engine in the recommendation generator can generate recommendations based on the student'"'"'s test results. The recommendation generator is coupled to a report generator and a question generator. The report generator accesses a report format. Based on the recommendations and the report format, the report generator generates a report, which can provide assessment of the student'"'"'s understanding in different areas of the subject, and which can provide action items to improve on the student'"'"'s understanding in the subject. The question generator, based on the recommendations, generates a number of questions. The student can take this new set of questions to further enhance her understanding in the subject.

23. An educational system for assessing a student'"'"'s understanding in a subject, which is divided into line-items, with at least one line-item being more difficult than another line-item, the system using the latest test results from the latest test taken by the student, the latest test including questions from a plurality of line item, the system comprising:
-
a score generator for accessing the student'"'"'s prior-to-the-latest test results, the latest test results, and the time that each test was taken to generate an overall score for each set of questions that belongs to the same line-item, such that each overall score reflects the student'"'"'s degree of forgetfulness as a function of time for that group of questions; an inference engine coupled to the score generator for; accessing a set of relationship rules, that define relationship among the line-items; determining the student'"'"'s level of understanding in each line-item in the latest test by applying the set of relationship rules on the overall scores; providing recommendation, which at least suggests to the student to work on one line-item; resolving conflict among one or more relationship rules with the overall scores, and conflict among two or more rules, if there is a conflict, so as to provide a consistent assessment of the student'"'"'s understanding in the subject; a report generator coupled to the inference engine for; accessing a report format; and generating a report, based on the recommendation and the report format so that the report can provide assessment of the student'"'"'s understanding in each line-item of the latest test; and a question generator coupled to the inference engine for generating a plurality of questions, which can be categorized into at least two complexity levels-one line-item being the one suggested by the recommendation, and a second line-item being different from the one suggested by the recommendation.

24. An educational system for assessing a student'"'"'s understanding in a subject, using the latest test results from the latest test taken by the student, the system comprising:
-
a test-results-storage medium for storing the student'"'"'s test results; and a score generator; for accessing the student'"'"'s latest test results; for accessing the time that each test was taken; coupled to the storage medium for accessing the student'"'"'s prior-to-the-latest test results; and for generating an overall score based on the accessed information; such that the overall score reflects the student'"'"'s degree of forgetfulness in the subject as a function of time. - View Dependent Claims (25, 26, 27, 28)

36. An educational system for assessing a student'"'"'s understanding in a subject, which is divided into line-items with at least one line-item being more difficult than another line-item, the system, using the latest test results from at least one test taken by the student, comprising:
-
a score generator accessing the student'"'"'s latest test results to generate overall scores; and a pre-requisite analyzer coupled to the score generator for accessing pre-requisite rules, which, based on the complexity levels of the line-items, establish a complexity-hierarchy among the line-items; and determining the student'"'"'s level of understanding in each line-item in the latest test by applying the complexity-hierarchy on the overall scores. - View Dependent Claims (37, 38, 39, 40)
