Not sure if you'll understand %100 of what I'm about to say but I'm hoping if you don't, you'll use a translation service to figure this out.
First, you need to start by setting your goals and making sure that you are committed to what you want to achieve. You have to practice regularly. Consistency is the key element. You need to dedicate time each day to practicing English, whether it's reading articles, writing passages or essays, or trying to speak English.
Next, there’s vocabulary. I suggest you make flashcards and/or take advantage of the free apps that can help you get more exposure to English. Start with these and then update us on whether this is working for you or not.
