Although there’s not a specific order for the Espresso English Academy, my suggestion is usually this:
Begin with:
- Vocabulary 1
- Everyday English Speaking 1
- 1000 Collocations
These are the most essential skills to build a good base in English. You can go one by one (finishing one course completely before continuing to the next one) or if you prefer more variety, you can take turns – do one vocabulary lesson, then the next day one speaking lesson, then the next day one collocations lesson, and repeat like this.
Then, continue to:
- Pronunciation & Shadowing
- Phrasal Verbs
- Confusing Words
- Vocabulary 2
These will help you improve your pronunciation, increase your vocabulary, and avoid errors with the words you already know.
Next, do these:
- Listening Course
- Everyday English Speaking 2
- Advanced English Grammar
- Advanced Vocabulary & Collocations Course
These courses are more challenging (especially if you use the “fast audio” in the Listening Course) and will teach you grammar in detail, as well as lots of informal conversational English.
Finally, save these for last:
- Idioms Course
- Slang & Informal English
These are good for more advanced students, after you already have a good foundation.
As for the Business English Course, this can be taken anytime, it just depends on your needs. If you actively need English for your current job, then you should study it earlier in the sequence; however, if Business English isn’t so important for you, then you can leave it until later.
