"The AI feedback on Read Aloud is genuinely accurate — it told me I was rushing on multi-syllable words. I fixed that and jumped from PTE 68 to 79 in 3 weeks. Completely free."
"Used MockMaster every morning for 6 weeks. The Writing Task 2 criterion feedback is better than some paid courses. Got Band 7.5 — exactly what I needed for AHPRA nursing registration."
