I would like to recommend review of every lesson in Mathematics, Physics and the Avi Ezri of Rav Shach 400 times before going on. This is based on the idea of the Gemara of 400 times review plus the idea of the Gra [the Gaon of Villna] that one needs knowledge of the seven wisdoms before one can know anything in Torah. He said, ''When one lacks knowledge in any of the seven wisdoms, that lack will cause a lack in understanding of Torah a hundred times more.'' [This I recommend for the sake of my son, IZHAK BEN AVRAHAM. And, in fact, Izhak held with lots of review. When I suggested, ''Just say the words and go on'', he did not agree.] The Physics and Mathematics is brought more openly in the Rambam in the Guide for the Perplexed in the Introduction and later in the parable of a king in his country. \
[The Gemara says, ''Anyone who does not review his learning is as if he buries his sons and daughters.'']
My plan is that after 40 days in a row of learning one page or section that then one goes to the previous page if that first one was not clear, or to the next of it was clear. but that whole should be reviewed 400 times.
ALSO to listen to lectures in Math Physics and the Avi Ezri and Rav Chaim of Brisk from experts.
Also I suggest some fast sessions to get through the Avi Ezri in total and through the basic core subjects in Mathematics and Physics, and 1/2 page of Gemara, Rashi, Tophot, Maharsha daily to go for the merit of my son, Izhak.
