IELTS has Academic and General Traning - 2 different writing tests. The Academic test is more suitable for you and all students who apply to go to universities, and it features 2 tasks, lasting for about 1 hour. These answers are handwritten. The first question involves interpreting a graph, table or diagram, and the next one involves a short 250-word essay answer as an argument or a discussion. These tasks are quite evenly matched, but depending on whether you will need to write out things by hand or you will be using a laptop, computer or tablet for writing at university. Either way, it is a good idea to practise both forms of writing, regardless of which method of assessment you decide on.
