Abstract:
A system and method for computer aided test preparation is disclosed. A user submits a weighted answer in response to a test preparation question displayed on a computer display screen. The system and method use the weight of the response to determine the frequency of repetition of that particular question in the user&#39;s subsequent test preparation activities. The weight may be an indication of the user&#39;s confidence level of his or her submitted response being the correct response to each question.

This application claims priority to U.S. provisional patent application serial No. 60/307,150, filed on Jul. 24, 2001. 
    
    
     FIELD OF THE INVENTION 
     The invention relates to the field of test preparation. More particularly, the invention may be embodied in a method and system for weighting a response by a user to a test preparation question and readministering the question to the user based in part on the weighted response. 
     BACKGROUND OF THE INVENTION 
     Throughout one&#39;s life, e.g., throughout the course of a student&#39;s academic career, or a businessperson&#39;s professional career, individuals are often required to take a variety of tests or exams for various reasons. For instance, high school students are often required to take a Scholastic Aptitude Test (SAT) or ACT Assessment (ACT) as part of the college application process. College students are often required take the GRE, MCAT, LSAT, or GMAT as part of the application procedure for a variety of types of graduate school studies. Adults, as part of their professional careers, must often take a professional exam to be allowed to pursue their chosen profession, for instance, a state bar exam to practice law in a given state, the patent bar exam to engage in practice with the United States Patent and Trademark Office (USPTO), or medical boards to practice medicine. 
     The examinations that an individual takes throughout his or her life may have a substantial impact on his or her career. For instance, individuals who score well on the LSAT tend to attend better law schools and obtain higher paying jobs than those who score lower on the LSAT. Likewise, the higher one&#39;s score on the SAT, the better college to which one generally gets accepted. As such, there is often much pressure on an individual to do well on any particular exam. 
     To help individuals study for such tests, test preparation materials and classes are commercially available. For instance, an individual preparing for a test can buy a test preparation book, attend a preparation seminar, or buy computer software, among other things. Computer software typically administers to a user a series of sample test questions to help the user prepare for the actual exam. However, the software is lacking in that the software generally presents the user with a question, accepts the user&#39;s response, informs the user of the correctness of his or her answer and why, and then proceeds to the next question. When the program finishes all the questions, the program generally either terminates or starts over, readministering the user the entire set of questions. 
     Some known software programs record when a user answers a question correctly. After answering a question correctly, the program typically does not re-administer the same question because the user already knows the answer. However, when a user guesses the answer to a question and guesses correctly, the software typically assumes that the user knew the answer just as with any other question answered correctly. As such, the program generally does not readminister the correctly guessed question unless the software program is readministering all the questions in their entirety. 
     Thus, a test preparation software program is needed that can account for when a user is guessing answers to questions, and readministers questions to the user based whether the user guessed previously in response to the question. 
     SUMMARY OF THE INVENTION 
     In a first aspect, the invention is embodied in a method for displaying test preparation questions to a user. A first question, to which a response is requested, is displayed on a computer display screen to a user. A weighted response to the first question is received from the user. When the user&#39;s response is correct, the previous steps are repeated for the first question when the weight meets predetermined criteria. 
     In a second aspect, the invention is embodied in a computer system adapted to present test preparation questions to a user. There is a processor and a memory containing computer readable instruction. When the computer readable instructions are executed by the processor, the computer is caused to perform a set of steps. A first question, to which a response is requested, is displayed on a computer display screen to a user. A weighted response to the first question is received from the user. When the user&#39;s response is correct, the previous steps are repeated for the first question when the weight meets predetermined criteria. 
     In a third aspect, the invention is embodied in a computer readable medium on which computer readable instructions are stored such that, when executed by a computer, they cause the computer to perform a set of steps. A first question, to which a response is requested, is displayed on a computer display screen to a user. A weighted response to the first question is received from the user. When the user&#39;s response is correct, the previous steps are repeated for the first question when the weight meets predetermined criteria.

     DETAILED DESCRIPTION OF THE INVENTION 
     In one embodiment, with reference to FIG. 1, the invention is embodied in a computer configured to present objective test preparation questions to a user preparing for a test, exam, or the like. An objective question is one to which the most correct response is one of a predetermined set of choices, for example, a conventional multiple choice question or true-false question. The computer  100  has a processor  102 , optional volatile memory  104 , and non-volatile memory  106  for storing application software  108  and a test question database  110 . The database  110  contains sample questions used in preparation for an exam. As used herein, a question may be an actual question used on a previous exam, a question constructed exclusively for purposes of test preparation, or any other statement presented to a user to aid in test preparation, where the statement requires a response by the user. For instance, questions relating to patent practice may be used in an embodiment of the invention directed to preparation for the patent bar exam. Sample questions are often available from the organization for which the test is required, which in this example the Office of Enrollment and Discipline at the USPTO or other government agency responsible for administering the exam. 
     In a first embodiment of the invention, as well as selecting a response to a question, the user also selects a weight, or confidence level, associated with the user&#39;s response to the question. For instance, in one embodiment, as shown in FIG. 2, a user selects one of two confidence levels. The first confidence level is that the user is sure his or her selected response is correct. The second confidence level is that the user is not sure that his or her selected response is correct. After submitting the weighted response, the program continues to operate based in part of the weight. 
     In this embodiment, application software may be configured to cause a computer to perform the steps shown in FIG.  3 . In step  301 , a question is picked from the set of possible questions to present to the user. Initially, this set may be the entire set of questions in the database  110 , or some subset thereof In step  303 , the selected question is presented on the computer display screen to the user. In response to the question, the user, in step  305 , selects a response to the question. 
     In step  310  the user selects a weight associated with the response, where the weight may represent the user&#39;s confidence in the correctness of his or her answer. The weighted response is submitted in step  315 . The system determines whether the response is correct in step  320 . If the response is incorrect, the system checks in step  335  whether there are any questions left in the question set to present to the user. If so, the system returns to step  301 . In this manner, the question that the user answered incorrectly remains in the set of possible questions, and thus the user may eventually be prompted again with the same question. 
     If the response is correct the system checks, in step  325 , the user&#39;s confidence level in his or her response. If the user was unsure of his or her response, the system proceeds to step  335 . If the user was sure of his or her response, the system marks the question to be removed from the question set in step  330 . The system then proceeds to step  335 , where it will determine whether there are any questions left in the question set. If so, the system proceeds to step  301  and selects a question from the remaining questions, and continues the process until no question remain in the question set. Optionally (not shown), upon successfully depleting the question set, a congratulatory message may be displayed on the computer display screen, informing the user that he or she has successfully completed the question set in preparation for the exam. 
     In some embodiments the system proceeds through the entire question set before repeating any questions. In other embodiments, the system may choose randomly from the entire set of questions such that it is possible that a question may be repeated before the user has seen every distinct question. 
     In another embodiment of the invention, as shown in FIG. 4, more than two confidence levels may be used. In this embodiment, one question may be presented to the user more often than another question, depending on the user&#39;s confidence level when responding to each question. The number of times a question is redisplayed to the user may be proportional to the user&#39;s confidence level during his or her initial response to the question. For instance, a question that a user responds to with a twenty-five percent confidence level may be subsequently presented to a user three times as often as a question to which the user responded with a seventy-five percent confidence level, even when the user responds correctly to each question. 
     When a question is redisplayed to the user after the user&#39;s initial weighted response to the question, the user selects a second response and a second weight associated with the second response. The second response may or may not be the same as the user&#39;s initial response, just as the second weight may or may not be the same as the user&#39;s initial weight selected for that question. The most recently selected weight may be used to determine the frequency with which the question is redisplayed. In another embodiment, all of the user&#39;s selected weights for a question are averaged together, and the average weight may be used to determine the frequency with which the question is redisplayed. In still another embodiment, the most recent n weights submitted with the most recent n responses to a question are averaged together, where n is an integer value greater than zero. The average of the most recent n weights may then be used to determine the frequency with which the question is redisplayed. In another embodiment, the confidence level percentage may be used as a weight for selecting which question to redisplay. That is, those questions with higher confidence levels may be readministered less frequently than those with low confidence levels. 
     In one embodiment of the invention, a time of response may be used as an indicator of the user&#39;s confidence level, without having to affirmatively ask the user his or her confidence level with respect to a question&#39;s response. Because it is readily ascertainable how much time an average person takes to read a question of a known length, the amount of time taken to respond to the question beyond the amount of time it generally takes to read the question can be used as a measure of the user&#39;s confidence level. For example, it may take an average person twenty to twenty-five seconds to read a short questions of about fifty words, including five short answer choices of one to two words each. If the user correctly responds to the question within about thirty seconds, it may be inferred that the user was not guessing. However, if the user correctly responds to the question but takes over one minute to do so, the test preparation software may infer that the user guessed in response to the question, even though the user answered the question correctly. 
     While the invention has been described with respect to specific examples including presently preferred modes of carrying out the invention, those skilled in the art will appreciate that there are numerous variations and permutations of the above described systems and techniques that fall within the spirit and scope of the invention as set forth in the appended claims.
