For multipule resonse such as 2 or more responses to a poll will give full credit or no credit at all (no partial credit/weighted grading).
For a multiple choice question: 4 of the 5 possible responses will be correct and be assigned one point total. If all four responses are selected with "Mark as Correct", and a student doesn’t select all 4 correct answers then they will receive a zero
We do have a weighted grading feature that can be enabled from our Features lab section. It’s pretty stable, but we do not have all the features we want in it yet to be completely released by default. You can turn it on and try it out by doing the following:
1. Click on the gear icon on the top right of the page and go to Settings
2. Select Features lab on the left side of settings
3. scroll down and click the Enabled button for Weighted grading
4. click the Apply labs settings button at the bottom of the page
Then for any Multiple Choice Poll you can go to Edit > and assign specific points for each answer choice

Example: 3 out of 5 answers are correct. I suggested the weighted feature, however, the instructor wants full points (if they select all 3) or no points (if they only select 1 or 2 instead of all 3). The green check mark for all 3 correct answer worth a total point value (1 point).
