An extension request must be made in writing no less than one week before the end of the semester. Not all extension requests are granted and are at the discretion of the TLC Coordinator. Documentation may be required to justify extenuating circumstances. TLC classes are standardized, but may vary somewhat from the grading shown below. Check your specific course syllabus.
Some courses have a project which replaces the midterm.
Also the percentage weight can vary. When you make corrections, first rename your new file xxx -cr1, where xxx is the original filename and the 1 is your first correction. Usually only one correction is needed, if you'll be careful not to add additional errors. Also keep the same extension, i.e. .doc for MS-Word, .xls for Excel, and .ppt for PowerPoint, etc. Refer to TLC Schedule for current semester deadlines.
