Summer life drawing

I'm taking an 8 week life drawing course this summer just to keep up the practice.  Once again the teacher's approach is different -- but I like that.  I like getting different suggestions and methods.  We began the first day by doing a 15 minute drawing.  We did one at the end of the class as well.  The teacher collected these to show us at the end of the term.  For the rest of the time we did very fast gestures beginning with 1 SECOND poses.  Here is one example of a page covered in many one second gestures.

For the second class we had a different teacher who taught us proportion.  I've had him before and still have the knitting needles I used to measure sizes and angles.  It's tricky to do and so easy to get confused.  Here are my first and fourth (last) drawings from that class.
