问题：我是看完***老师的revenue recognition来做这道题的，视频内容很清楚，但是没有 cover到这种比较细致的题目。 我的疑虑是：我需要停下来看书然后攻克这类题 还是 暂时先跳过等到下一阶段复习阶段时再看书？ PS:现在是我第一遍听课和做题,我的习惯是看一段视频 配套做金程网站上的题目。不知道这样好不好，就是遇到比较细节的题目是先放过还是进入原版书的查阅（但问题是如果每一道都看书 会打乱学习节奏 就是时间来不及；但是如果不做题，只听视频 感觉等于没听 能理解但是不会做题） 原题：Builder Co. enters into a contract with Customer Co. to construct a commercial building.
