QUICK ANSWERStart with the tool that matches your immediate input.
Open IELTS Grammar Practice Test first when its stated purpose matches the result you need now. Use TOEFL Grammar Practice Test only when it solves a separate next task.
This guide is for language learners, students, travelers, and job seekers. Start with IELTS Grammar Practice Test when your immediate task is to take the IELTS Grammar Practice Test and receive an instant, clearly explained result. Move to TOEFL Grammar Practice Test only when you also need to take the TOEFL Grammar Practice Test and receive an instant, clearly explained result.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether TOEFL Grammar Practice Test solves a genuinely different next step.
Both tools sit in Language & Learning Tests, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
