IPS.....stands for "Introduction to Physical Science"!!! Attached is our 2 semester syllabus. If you check grades on Powerschool and notice letters instead of grades, they are codes for the following: nhi- "not handed in", abs- "absent", unex- "unexcused absence" (zero credit). Any blank spaces in the grades mean that those grades have not yet been entered. If you need to contact me, I am available from 1:00 p.m. to 1:45 p.m. and after school.
