Yup. This looks like a grant sponsored exercise in semi-vanity publishing and a thinly disguised series of blog postings which are loosely tied together to form a book, which doesn't work as fiction (since it has no focus) and a case of bait-and-switch (since it barely covered the actual theme of PSLE)
In the end it just promotes gender inequality since the poor older daughter doesn't make it (PSLE) and the son, Noah gets away with being, well, the son and boy (pats on the head - mommy loves you)
Definitely to be avoided.
