How strict are absences in a community college summer session course?

I’ve been looking on the site, and I’m planning on emailing at professor, but I wanted to get a general idea first, in case it is really strict, so I don’t make a bad first impression email.

So can someone give me a general idea?
(I’m not planning on skipping out on class, but it looks like my great grandmother is requesting my presence smack dab in the middle of the class session. one does not refuse the great grandmother anything unless it really is a matter of life or death in my family)

What has been your experiance?
