When you start learning English, or if you want to improve your English, one of the best things to do is to be able to speak with a Native Speaker.
Practicing English with Native Speakers will force you to speak English, because you can only communicate in English, no matter your level. Learning English with a Native Speaker will give you an unparalleled advantage. Native Speakers are more able to understand which areas you may struggle with and guide you to improvement.
Practicing English with Native Speakers, will be expose you to more idioms, dialect, slang and a generally more extensive vocabulary than with a non-native speaker. Too much slang is, of course, not a good thing, but exposure to this side of the language is always useful to understand what people really mean.
Try it and be confident, don’t be stuck with boring textbooks!
