Difficulty depends on your comfort. The TOEFL exam pattern includes longer academic passages, while IELTS has mixed academic + general topics. For writing, using an IELTS essay checker helps improve your structure and identify weak areas, which can indirectly boost your TOEFL writing skills too.
To cover the TOEFL syllabus thoroughly, you should follow a structured study plan that focuses on one skill at a time, then practice integrated tasks. I provide personalized plans and mock tests to ensure each section is well-prepared.
