Where the marks are in the explanation.

An ICSE paper asks a student to write more, and to write it properly. That makes the checking slower for a teacher, and it makes it a harder and more interesting problem for software than a CBSE numerical.

Longer answers change what has to be read

A CBSE three-mark numerical has a shape. An ICSE answer of the same weight is frequently a paragraph, and the marks are distributed through it — a point here, a justification there, an example that either lands or does not.

Checking that is not a matching exercise. It means reading the paragraph for whether each thing the scheme asks for is actually present, wherever in the answer the student put it, and in whatever words they chose. That is the job, and it is why every mark we return quotes the sentence that earned it — a mark on a long answer that cannot point at its own evidence is not checkable by anybody.

What this means in practice

• Points found anywhere in the answer. A student who answers the third part of a question first is not penalised for the order.
• Credit for the student’s own wording. ICSE rewards expression; the scheme is read for the idea, not for a phrase match.
• Literature and English answers marked for whether the reading is supported, with the supporting line quoted back.
• Science and Mathematics still marked step by step, with error carried forward, exactly as for CBSE.
• More pages per student. An ICSE paper is simply longer, which is worth knowing when you work out volume — it moves the arithmetic on our pricing page.

ISC, and the honest limit

ISC answers at Class 11 and 12 get longer and more argued still. The consistency advantage grows there — a marker on their fortieth paper at midnight is not applying the same standard as on their first, and software does not tire. But the judgement calls get harder too, and more answers come back flagged for a teacher to decide rather than marked outright.

That is the correct behaviour, not a failure: an answer that argues something unusual and correct is exactly the one you least want auto-marked. Our position on where this should and should not be trusted is set out here.
