To all classes:
Due to the impending arrival of Hurricane Sandy, Mayor Bloomberg has announced that on Monday all public schools will be closed. The decision regarding the closure on Tuesday will be made based on the weather condition on Monday.
For Chemistry classes: If we have school on Tuesday, the exam will be held on Tuesday. If we do not have school on Tuesday, then on Wednesday we will be having the exam (in Rm. 336). The lab. on Wednesday will be moved to Thursday.
For Earth Science classes: The lab. on Wednesday may be moved to Thursday; we will see how it goes.
Stay Safe,
Dr. Liu
