Abstract: An apparatus with a memory that has a learning database and a user database. The learning database has a set of details to be learned and the user database has a user profile. The user profile has a weighing vector of weighing parameters corresponding to the set of details. The apparatus further has a processor configured to test a user for particular details in an order that is at least partly based on the weighing parameters. The processor is further configured to adjust the weighing parameter corresponding to a given detail depending on whether the user has passed the test. Also corresponding methods and computer programs are disclosed.

Abstract: A method for training involves maintaining a plurality of details to be tested; maintaining group definitions which define a plurality of groups associated with two or more of the details; determining a test detail; outputting to a user a question to which the test detail is a correct answer; inputting from the user an answer to the question; determining whether the answer comprises more than one parts. If yes: determining other details belonging to a common group with the test detail; determining which if any of the test detail and of the other details match the parts of the answer and considering such details as correctly answered details; and storing for each correctly answered detail an indication of a correct answer. If the answer comprises no more than one part, then: determining if the answer correctly matches the test detail; and if yes, storing an indication of a correct answer.
