good job but can be better

That´s one of my best App to learn english and I think this can be the best App in the Store. For that i have any suggestions:

1. Please add more questions (approx. 20 questions are not enough)

2. More tutorials

3. In the test section: please add the possibility to have a test with only irregular verbs and so i won´t need to buy another App for that.

4. Support for multitasking. When I go to another app and I come back, the App always start at the beginning.Please fix it.

So these are my important points. So if you optimize these points you´ll get the next two stars.
