                    <li>Fill in the scores per criterion for each student. You can see the student's final score in the last column.</li>
                    <li>Click 'Publish Assessment' if you are done. Click 'Save as Draft' if you have not finished assessing the activity. You can come back later if you need to make any updates.
                    <li>Unpublished results will be isolated. That is, they <strong>will not</strong> be aggregated to other results.</li>

                <ul>
                    <li>If a particular criterion cannot be assessed for a student, select "N/A" (Not Applicable). This <strong>will not</strong> affect the student's score.</li>
                    <li>If a particular criterion was assessed but the student did not complete the necessary work, you must select "0". This <strong>will</strong> affect the student's score.</li>
                    <li>If a student did not complete any work for this activity, select "0" for all columns in that student's row.</li>
                    <li>If a student dropped the class, select "N/A" (Not Applicable) for all columns in that student's row.</li>
                    <li>Cells with "N/A" <strong>will not</strong> be used to determine whether a criterion is achieved. Only scores from 0 to 8 will be considered for this purpose.</li>
                    <li><strong>At least one score must be from 1-8.</strong> Otherwise, the 'Publish Assessment' and 'Save as Draft' buttons will be <strong>disabled</strong>. If you want to delete previously saved scores, go back to the activity and click the "Delete Assessment" button.</li>

                    <li>Las celdas con "N/A" <strong>no</strong> serán utilizadas para determinar si un criterio se alcanzó o no. Solamente las puntuaciones del 0 al 8 serán consideradas.</li>
                    <li><strong>Al menos una puntuación deber ser del 1 al 8.</strong> De otra manera, el botón para guardar <strong>se desactivará</strong>. Si quiere borrar los resultados del avalúo, vuelva a la actividad y oprima el botón que dice "Delete Assessment".</li>
