Approach to writing answers in the exam

Hello Sir! My query is regarding the approach to answering the exam questions. If we answer the way we tend to understand and explain in our own words. Would it be considered the right approach? (Even though the examiner's answer doesn't match in terms of vocabulary?) But you have got some connection to the examiner's answer. Eg. in the software selection, The examiner's answer to selection would be the negotiation between the 2 parties who live in different countries. While my approach would be Location - The 2 parties are situated in different countries and therefore their commercial laws in the contract would differ leading to negotiations. Would it be the right approach? Thank you.
