The most efficient option for clients who would like to learn languages also to use it in their job (see far more can be found at www), is to combine supermemo with acquiring for instance a conversation partner. Due to this kind attitude they are provided with a recommendable opportunity to test recently learned material in practice. If we don’t have a partner, who would make us aware of our mistakes, we may learn (more learn polish) speaking inappropriately. However, in case of grammar and vocabulary, learning with supermemo can be substantially more efficient. It is so, because we are responsible for scheduling our work and depending on how much time we have, we can learn either more or less. Furthermore, the above analyzed alternative has been designed with the awareness of the fact that people tend to forget recently learned issues.
