One focused weekly class can be enough if the practice between classes is real.
For many Cambridge 0580 students, one 1.5 hour focused tuition class per week plus assigned practice is a workable rhythm. The class gives structure, correction, and method. The independent work turns that correction into habit. If the student attends class but does not practise, even extra hours can feel surprisingly ineffective.
More hours may be useful when the student has deep foundation gaps, an exam is close, or school pace has moved ahead of the student's current method. But those hours should have a clear purpose: algebra repair, exam-question interpretation, layout correction, or targeted topic recovery.
