While the Melamed Academy may have Judaic course suitable for the younger grades, I don’t think it can compare to a brick and mortar yeshiva.. It relies on the parent supervising the child’s time to insure he performs the work Staring at a computer screen for 8 hours a day may result in vision problem. They will also be lacking in social skills. It is doubtful he will be able to learn in a Bais Medrash or College or even be gainfully employed.
If you are looking for a cheap alternative to the high cost of yeshiva education, go to Rochester. They claim they can give all your children a world class yeshiva education for $1,000.00 a year. That is assuming you move there. Maybe you can find a job there or commute it only 4 hours from Monsey. Houses are cheap there. It’s worth looking into.
