I don't think they are calculated into your GPA. The schools, however, do receive a copy of your transcript and too many Ws do not look good!
Grades Excluded from Conversion
Withdraw, Withdraw/Pass—only if the issuing school considers the grade nonpunitive
Incomplete—only if the issuing school considers the grade nonpunitive
Those given for remedial courses only if the transcript clearly indicates they are remedial
Those awarded after the first undergraduate degree was received
Those assigned no measure of credit by the granting institution, regardless of the grade. Physical Education, Practical Art, Practical Music, and ROTC courses that are assigned credit will be included in the LSDAS summary even if the granting institution does not include these courses in its calculation of a GPA.
Passing grades from systems of one or two passing grades (e.g., Pass/Fail, Satisfactory/Unsatisfactory, Credit/No Credit, or Honors/Pass/Fail, High Pass/Pass/Fail), and those for which conversion rules cannot be formulated, including courses for which a transcript gives only narratives or descriptions. Credits for the work in these courses are totaled and reported separately as unconverted credits.
Grade symbols that have multiple meanings at the issuing school and the issuing school’s registrar is unable to confirm whether course credit was attempted (such as NC=either No Credit Attempted or No Credit Awarded, etc.). The total number of credits usually assigned to the particular type of course will appear on the applicant’s LSDAS summary, but will not be included in the GPA calculation.
Withdrawal grades that signify failure (such as WF=Withdraw/Fail, WU=Withdrew Unsatisfactory, WNP=Withdrew Not Passing) if the issuing school considers the grade nonpunitive. The total number of credits assigned to these grades will appear on the applicant’s LSDAS summary, but will not be included in the GPA calculation.
The original grade for a repeated course when the transcript does not show both the grade and the units for the original attempt. The total number of credits assigned to these grades will appear on the applicant’s LSDAS summary, but will not be included in the GPA calculation.
A No Credit grade that does not signify failure and for which no attempt at credit was made (e.g., NC=No Credit/Withdraw, or NC=No Credit Attempted).
I'm confused about the thing w/ W's. I've withdrawn from a couple classes w/ various reasons and they're on my transcript but they don't affect my GPA, etc. My school doesn't designate why I dropped or anything, how are these calculated?
