* Shemirat Shabbat KeHilchata (chap 28, note 206 and in new editions 220) quotes Rav Shlomo Zalman who was in doubt regarding whether it’s considered Hachana to study secular subjects not for the knowledge but only to do well on a test during the week. 39 Melachos (vol 4, pg 982) rules that it’s forbidden because of Hachana. | |||
* Yalkut Yosef (Shabbat, vol 2, pg 216) rules that one may only learn Torah on Shabbat and the only exception is a medical student who has a test after Shabbat and is pressured for time to study medicine (except for the study of surgery) on Shabbat. Though in that one case where it is permissible to learn secular studies on Shabbat it is only permitted with regards to Hachana. | |||
* However, [http://www.ravaviner.com/2010/01/studying-secular-subjects-on-shabbat.html Rav Aviner] permits study for a test on Shabbat if one enjoys the learning and doesn't cause one stress. </ref> | |||
