Time limit on when I can take CSWA test?

Two or three weeks ago, during a slow period, I requested andreceived a password to take the CSWA test. Almost immediately afterreceiving the password from Tangix, I was swamped with work. Now Idon't have the allotted 3 hours to take the test right now, plusI'm taking a vacation next week. Is there a time limit afterreceiving the password on when I can take the test? I still want totake it, but I just don't have the time now.SolidworksGeneral
