Many international graduate students need to take both the GRE and an English proficiency exam. Luckily, there are ways to study for both of these tests at the same time. In fact, the IELTS and GRE are similar in quite a few ways.
Study for IELTS Writing and GRE AWA at the same time
IELTS Writing Task 2 and the GRE AWA’s Analyse-an-Issue Task are almost exactly the same. Both tasks involve writing your opinion on a social issue — something like global warming, funding for education, etc. In addition, almost all GRE AWA questions have the same format as an IELTS Task 2 opinion/point of view question. (This is the most common of the 3 main types of IELTS Writing Task 2 questions.)
The main thing that separates IELTS Writing Task 2 and the GRE AWA Issue task is difficulty. GRE AWA is harder than IELTS. The GRE’s issue topic has a 30-minute time limit, and successful responses are usually 500-600 words long. In contrast, IELTS Writing Task 2 has a 40-minute time limit, with a recommended word count of 250-300 words. So on the IELTS, you analyse an issue in less detail, and you have more time to do it.
Because of this difference, it’s a good idea to treat IELTS Writing Task 2 as a warmup for the harder — but similar — GRE Analyse-an-Issue essay. As you get more confident with your IELTS writing, you can even rewrite a shorter IELTS Task 2 response, changing it into a GRE Issue response. From there, you can work on mastering your GRE writing skills in both AWA Tasks (Issue and Argument), while strengthening your IELTS writing abilities.
You can also use IELTS Speaking to refine your writing skills in IELTS Task 2 and the GRE Issue topic. The Speaking topics on the IELTS don’t explore social issues in the same way as IELTS or GRE essays. But IELTS Speaking does require you to quickly think of your personal opinions and views, and express them clearly; this is especially true in part 2 of IELTS Speaking! So your IELTS Speaking practice can help you think quickly about your opinions within the time limits of GRE AWA and IELTS Writing.
Study for IELTS Reading and GRE Verbal at the same time
The sentence completion in IELTS Listening and reading is easier than the sentence completion in GRE Verbal. But SC on both exams involves the same basic skill — understanding the way that vocabulary fits into a sentence’s context.
And speaking of vocabulary, the IELTS does not have any questions that directly ask about the meaning of vocabulary words, while the GRE does. However, the readings on both IELTS and GRE have almost the exact same difficulty level. In fact, the level of IELTS vocabulary and GRE Reading Comprehension vocabulary are about the same. Only the GRE’s shorter sentence completion readings are consistently harder than IELTS reading.
The thing that really makes GRE Reading Comprehension harder than IELTS Reading is the questions. The GRE is much more likely to ask questions about theme, subtext, and author attitude than the IELTS. However, the IELTS will also touch on these question types. So again, what you’ll want to do is start out by building IELTS skills, and then go on to practise the harder GRE Verbal materials as well.
Study for the IELTS and GRE Quantitative at the same time
Believe it or not, some IELTS skills can be used in GRE Quantitative. This is because GRE math includes graphics — charts, tables, and so on. The IELTS also has a graphics component. IELTS Writing Task 1 asks test-takers to write a description of an infographic. And IELTS reading includes some reading activities with diagrams and charts. To sharpen your skills with English language infographics, it can help to study IELTS Writing Tasks 1 and the visual parts of IELTS reading while you also study the GRE’s visual math content.
Here, the GRE exam is not necessarily “harder” than the IELTS. Math and reading comprehension are two very different skills, and it’s hard to compare them directly. It is worth noting that IELTS visuals are often more complicated than GRE math visuals. So you may want to practise reading the GRE Quant infographics before you move on to practise with visual information on the IELTS exam.
