Are the General English Exams easier?
No, in a word. The B2 First and the B2 Business Vantage are the same level, and the C1 Advanced and the C1 Business Higher are at the same level. They are all difficult but in different ways. The most obvious difference is that the Business exams do not have any explicit grammar questions. The General English exams, have one section worth 12 points which is more or less grammar only.
What usually scares people about the Business exams is the vocabulary. They worry that the texts or the listening will contain lots of vocabulary which they do not understand. Well, I have two things to say about that.
1) If you already use English at work or use English more for professional reasons than social reasons, then it is likely that your Business English vocabulary is much better than your General English vocabulary.
2) The other is that any vocabulary that you learn for the Business English exams will be a lot more useful for you in the future, than the General English vocabulary. Also, you can expand and practice your Business English vocabulary in a focused way using the BEC Exam Guide resources pages for B2 Vantage and C1 Higher which recommend two books (for each exam) to help you with your vocabulary.
To support my two points above, let’s have a quick look at two example questions. They are exactly the same type of question where you have a text full of gaps and you have to choose the correct word from a choice of four. The first example is from a B2 First exam paper, the second is from a B2 Business Vantage exam paper.
