In my experience, time pressure is often a huge concern for both IELTS and PTE candidates. The factors contributing to this stress are:
- How to get started?
- What to write?
- Choosing the ‘right’ words?
- Check spelling!
Therefore, your choice of exam is important in respect of how long is allowed for the essay-writing. Options are:
- PTE which allocates 20 minutes to write, 200 – 300 words.
- IELTS, both computer-delivered and paper-based, which allocate 40 minutes to write a minimum 250 words.
After that, both marking marking criteria are very similar so therefore time allowed becomes an important difference.
