局限性

–Course pricing varies by program and is not fully transparent until you talk to sales or log in
–Heaviest focus is on IELTS/TOEIC/HSK, so it is not ideal for learners targeting other exams or general fluency only
–Effectiveness still depends on learner discipline; AI feedback on ideas and logic is helpful but not a substitute for expert human tutoring
–Some testimonials and score banners are marketing-heavy, so results should be judged against your own baseline and study time
