We asked students as we will this year to describe themselves based on gut instinct early on, do you consider yourselves among those less comfortable with computers or just the mere idea of being in this class?

我们给学生提过这样一个要求，以后也还会再提这个要求,那就是凭直觉描述一下自己，你们是否认为自己不擅长电脑,还是只是单纯地想来上这门课？

So-- if you don't feel comfortable doing it, don't do it-- what I'd like to do now is as following: Take your thumb and your middle finger and create as much as possible a 90 degree angle.

感觉不舒服的，就不要做，希望按下面的指示做：,让你的姆指和中指,尽可能形成一个直角。

And similarly, particularly for those less comfortable, do we offer prior to the start of each week for a new piece at what we dub a walkthrough whereby one of the teaching fellows will literally start on the first page, give you a mental framework for the week's problems and talk about the ideas that it covers, and then walk through the piece set so that you have a roadmap of sorts that you can follow.

同样，特别对于那些不熟悉编程跟不上进度的同学，每周上课前都可以预习新的知识点,一名教师从第一页开始,对于每周的问题,都给你们简历一个心理框架,并讨论它所涵盖的思想，然后了解了每个部分之后,就可以有个学习的路线图。
