Class 7 is the year nobody watches
Class 6 gets attention because everything changes. Class 8 gets attention because it is the final year before Secondary School and promotion rules are stricter. Class 9 and 10 are obvious priorities. Class 7 sits in the middle with nothing to draw a worried parent's eye, which is why it is the year we are most often asked to fix retrospectively, two years later.
The problem is straightforward. In Class 6, everything was new. Your child who did not understand something either said so or looked confused. In Class 7, the same topics come back and are assumed knowledge. A twelve-year-old who never actually understood why two negatives multiply to make a positive can memorise the rule, apply it correctly all year, and earn perfectly respectable marks. No one catches this gap because the marks look fine.
The problem surfaces in Class 8, when algebraic identities and factorisation force your child to manipulate signs within a structure, not just apply a rule to simple sums. Now the gap is two years old and sits underneath subjects that have already moved on twice.
The practical case for supporting Class 7 is not that the year is difficult. It is that fixing Class 7 is affordable, and fixing Class 9 is not.
