    • There is no class meeting on this date. This time is for making sure you have everything submitted, and issues identified and resolved.
    At some point Thanksgiving week, IT required a password reset no my email. The Portal changed that week too. For whatever reason, my YCP email to off-line folders no longer works. Thus, all submissions need to be sent to robinsnyder@gmail.com with the proper subject line and attachments. Any submissions sent to rsnyder9@ycp.edu will not be accepted.
    End of semester cutoff dates: (announced 2019-11-26, posted 2019-11-28)
    • Sat, Dec 7: All work graded and posted
    • Mon, Dec 9: Any scoring issues need to be raised via email with subject line I1 (for Issue submission #1). Please raise only one scoring issue on each submission. After Dec 9, scores for any scoring issues not raised via I1 submission will not be changed.
    • Tue, Dec 10: Last CS 340 class date. No class. Use time to resolve any work or scoring issues..
    • Wed, Dec 11:All I1 scoring issues resolved and posted.
    • Thu, Dec 12: CS 340 final at 1015 for class meeting at TR 1100.
    • Sat, Dec 13: Any scoring issues on I1 scoring issues (meta scoring issues) need to be raised via email with subject line I2 (for Issue submission #2). After Dec 13, scores for any scoring issues not raised via I2 submission will not be changed.
    • Sat, Dec 14: CS 340 final at 0800 for class meeting at TR 0930.
    Note: F1 (final exam) is 2019-12-12 at 1015 (1100 section) or 2019-12-14 at 0800 (0930 section).

    Note: Q11 is a bonus quiz for immediately after you finish the final exam. It is intended to cover the last two lessons and provide an additional quiz drop for those that might need and/or want such a drop.
