The way Rav Nahman said to learn Torah was to say the words and go on. [See Conversations of Rav Nahman 76. Also there are places like the Le.M I perek 12 which indicate the same idea::דע כי על ידי אמצעות הדיבור יכולים לבוא לתבונות התורה לעומקה. The LeM is the major work of Rav Nahman.
This approach I found to be the only way I could learn Physics and Math also.
But it took me a long time until I stated applying this method to Physics. My parents had always been very pleased when I showed interest in Physics, but until I saw this in the חובות לבבות and also Maimonides the message did not really sink into me.
But I should add the idea of review ten times as away of doing one's in depth sessions. This I heard in Shar Yashuv by Rav Freifeld. And the in depth session should be in the morning and the fast sessions in the afternoon as they do in all Litvak yeshivot.
