Hi, here is my easy 4 step plan for you using Italki.
1. Once you've logged onto Italki, click onto Learning a Language = English. Click in your own language below.Look at the native speakers & feel free to email them and ask for help/advice.
2. Click onto the Files, Resources & Knowledge sections & complete the exercises provided for you.
3.Click onto Groups & join an English Learning Group and find a language partner.
4.Keep a notepad by your computer to write down any useful expressions that you see. Good Luck!
