To be honest, I think the best way to learn a language is to practice with a teacher often. In my classes we do grammar exercises in addition to practicing speaking. The way to get better at speaking is to speak often. Exposing yourself to English books, music, movies, tv shows and podcasts are also great tools. Often textbooks don't teach how actual native speakers speak. Which is why exposing yourself to native speakers and classes are helpful. I hope to meet you soon. I am available on instant lessons and have time this week in my schedule.

I'm a native speaker Kinya but I always advice my students to watch movies in English with subtitles, listen to English music and practice reading aloud and speaking, doing all of this will help you improve your grammar

Studying grammar won't help you speak. You need grammar, but if you don't practice, you won't make the right connections between rules and usage. When you put the language to use through speaking regularly, that's when you improve. Even if you make mistakes, you learn from the mistakes. So look for people to have voice conversations with, whether they are native or non-native speakers. You need to use the language as often as possible.

Chat with a person who speaks English as his/her second language as well. This won’t be to stressful comparing to speak with a native speaker.

I think that the best way to improve speaking skill is to talk with native speaker regularly. To practice English grammar, booking systematic classes is achievable.
