IVT - Irregular Verbs Trainer

What's new:
- New learning algorithm
- New start-up look and feel
- Beginner, Basic and advanced modes.

How it works:

When You enter correct verb forms IVT (Irregular Verbs Trainer) goes further and give You next verb to test. But when You enter incorrect verb forms IVT add two repetitions of this verb:
- first verb close to Your learning position (after two or three other verbs to learn)
- second verb at end of lesson

If You remember valid verb forms for a while, but forgot it at the end - You have another two repetitions. There is no way to leave lesson without new verb forms deep in Your memory :)
