One focused weekly class can be enough if the practice between classes is real.
For many Cambridge 0580 students, one focused 1.5 hour tuition class per week plus assigned practice is a workable rhythm. The class gives correction and method. The practice turns that correction into habit. A student who attends class but does not practise between sessions will not make much progress, even with more hours added.
More hours can help when foundations are weak across several topics, when an exam is close, or when school has moved ahead of what the student can actually do alone. But those extra hours need a clear target: algebra repair, question-reading habits, layout, or a specific topic gap. Hours without a target rarely fix the problem.
