Before you think about speaking with a language partner, consider a few things:
-Is your level of listening good? When you watch TV shows can you understand at least 50% of what they say? Can you spell a word you've heard but don't know?
-Do you understand the basics of grammar and verb conjugation? This doesn't necessarily mean knowing exactly when to use past perfect vs past continuous (I didn't learn how to use the different past tense verbs in French until I started talking). It means, can you conjugate verbs quickly? Can you use question words (when, why, how, if, etc.) correctly? Do you understand word order?
-Do you have basic vocabulary memorized? This doesn't mean "Can you understand most basic vocabulary when you read something?" It means, if you want to say a basic sentence like "I need to eat soon." with key verbs, adjectives, adverbs, etc. can you do it quickly? Or do you have to think about every word when you want to say something basic?
