If you are unable to complete a class, it is your responsibility to withdraw formally.
The Texas Education Code 51.907 limits the number of classes a student may drop in their undergraduate career to no more than 6 classes, unless your drop reason qualifies as an exception.
Once you have accumulated 6 non-exempt drops, you cannot drop any other classes with a ‘W’. Therefore, please exercise caution when dropping a class in any Texas public institution of higher learning.
Before you drop a class consider talking with your instructor about options and/or discuss it with your advisor.
