The invention relates to a foldable study card system for use as a study aid, comprising one or several information fields (1) which are suitable especially for receiving questions on the front (F1, ...) and the corresponding answers on the back (A1, ...). Questions, answers and other information can also be fixed to the main body (9) of the card system. By means of a fold (2) the information fields can be folded from the front and back by as much as approximately 180 DEG both to check the information written on the other side and to insert them into fastening elements (3) provided for this purpose. Information fields containing information which has been successfully learned and thus fastened cannot swing back but can be detached without being damaged. To make it easier to fasten the information fields and hold said information fields for folding them back and forth so as to check solutions, the invention provides for a fold (4) which extends from the upper to the lower side of the information fields and is positioned in such a way that an information field folded by approximately 180 DEG along this fold lies against and in front of the corresponding fastening element. |
