GoPost Credits



You may submit a solution to a HW problem, a review of someone else's solution, or a correction to Fulton's book.

When you first log into GoPost you have to choose a username and a password. Your postings will be indexed by "From: your username", so if you don't want others to know your identity, choose a username accordingly. (Of course I will know your identities, but not your passwords).

Here is how it works:

For "normal progress", you SHOULD submit at least one SOLUTION of difficulty 3 or more and at least one REVIEW per week.

Your final grade will be based on your participation in the class. The points given here are indicators of your participation, but they are mainly for showing how important these different activities are compared to each other. I will not give grades strictly on points accumulated. I want you to work on these problems and if you convince me that you did, you'll get a good grade regardless of the actual number of points you received. Of course if you accumulate a lot of points you convince me that you're working hard. Notice that potentially the largest one submission "gain" can be achieved through constructive suggestions to improve Fulton's book.

Before you submit a CORRECTION to Fulton's book, check to see if it has already been submitted. If you submit a new one you receive 1 point for a typo and 2-50 points for constructive suggestions (e.g., "there's a logical mistake here, and here is how to correct it" or "it would be much better for the reader if this proof was phrased this way")

If you submit a SOLUTION to a HW problem, you will receive the number of points listed for the problem on the HW list.
You may submit solutions to problems that have already been "solved" by others. I ask you, however, not to copy an already submitted solution. If you'd like to keep working on a problem, do not look at a submitted solution until you have your own.
You may work in teams, in which case please include the team members' username with the submission. Do not submit multiple copies of the same work. If you have a group that works together regularly, then you may register a username for the group and submit the solution under that username. In this case let me know who is included in the group.

If your solution is reviewed by someone and found correct, you will receive an additional 2 points. You cannot review your own work. If it is reviewed and found incorrect you will lose some points based on how serious the error is.

To write a REVIEW, you have to decide whether the solution is correct or not and be able to support your opinion. The first (submitted) REVIEW of any solution is worth 1-3 points if correct. However you lose 1 point if you say a solution is good when it is not (in other words you get -1 for the review). You may submit a review for a solution that has been reviewed only if the first review is less than a day old. The second review of the same solution is worth 1-2 points, the third is worth 1 point and any subsequent one will have only intellectual value. However, if you disagree with a submitted review, you may submit a "competing" review at any time.

Check the instructions on how to submit and please use the guidelines.
