You can take the PTE Academic exam as often as you'd like, but there is a mandatory 5-day waiting period between each attempt. This means that if you do not achieve the desired PTE score for Australia on your first attempt, you must wait at least 5 days before retaking the test.
It is important to plan your PTE exam dates carefully, especially if you're aiming for a specific PTE score for Australia to meet university or visa requirements. Many students take the exam multiple times to improve their scores. However, it is advisable to focus on preparation to avoid multiple retakes and reduce the pressure on the exam day. Preparing thoroughly before your first attempt can save time, money, and effort in the long run.
Be sure to check your score after each attempt and assess which areas need further improvement. You can use mock tests and study resources to strengthen weaker sections before retaking the test.
