Boards
Curriculum-aligned practice for the board your child is already enrolled in — following the school's sequence rather than competing with it.
CBSE
Practice mapped to the CBSE sequence, from Class 1 to Class 10 — following the school's order, and reporting what your child actually understood.
IB
Practice for the IB Primary Years and Middle Years Programmes, built around explanation rather than recall.
A board is not a choice a parent makes on Sophoz. It is the syllabus their child is already sitting inside, set by a school that decides the order and the pace. So practice that ignores that order is worse than no practice at all: a child asked to work on something their class will not reach for another two months learns mostly that the tool does not know what they are doing.
Sophoz follows the sequence. Each board is mapped to a skill graph — the individual things a child has to be able to do, and which of them depend on which. When a child struggles with equivalent fractions, the graph knows the prerequisite is a secure grasp of multiplication as scaling, and practice moves there rather than repeating the same question with different numbers.
That mapping is also what makes the weekly parent report specific. Instead of "62% in fractions", it can say which step the child skipped, quote what they actually wrote, and name the misconception in a sentence a parent can act on over dinner.
Boards differ more than they appear to. CBSE and IB do not merely cover different content; they ask different kinds of question and reward different habits of explanation. Each board below describes how Sophoz approaches it and who it suits.
