Questions may use audio with a possibility to listen at different speeds. Questions may refer images (e.g. diagrams) to illustrate the question. An answer can be entered by selecting a variant or by entering an answer as text. The Trainer contains both simple and sophisticated answer processing engines. The edit field of the software can accept sentences, words, letters, digits. Comment system may show the exact place with mistake helping to find the correct answer.
