No on said it was easy, it does however continue to disprove your statement that there were no day schools in he US prior to WWII and that they did not serve girls
Members of my extended family have attended both day schools I mentioned in CT and Mass.
BTW, in my father’s generation (born 1920) day schools, elementary Yeshivos were not considered so important, the kids went to public schools and learned Torah from 2:30 on and Sundays with private tutors. In my father’s case he learned/was taught by his paternal grandfather who was educated at Brisk in what is now Belarus. My great great grandfather had a storefront school on 15th Ave Boro Park from 1925 until his death in 1938. Most of the students attended public school in the morning. They went on to a year or 2 of full time Yeshiva after high school then college and professions or business. They became successful enough to help found the modern day schools of the post WWII era
