Along with the total score, we want to get each question's score to go to the spreadsheet. Here is what we are trying to have:

You can try with Apps Script. I tested the following script that can give you an idea on how to achieve this.
const TARGET_SPREADSHEET_ID = "spreadsheetID"; //Change according to your needs
const TARGET_SHEET_NAME = "sheetName"; //Change according to your needs
const SOURCE_FORM_ID = "formID"; //Change according to your needs
//Run this function only one time, this will create a trigger that will run function "onFormSubmitTrigger" whenever a student submits a response.
function installOnFormSubmitTrigger() {
const form = FormApp.openById(SOURCE_FORM_ID);
ScriptApp.newTrigger("onFormSubmitTrigger")
.forForm(form)
.onFormSubmit()
.create();
}
function onFormSubmitTrigger(e) {
const targetSpreadsheet = SpreadsheetApp.openById(TARGET_SPREADSHEET_ID);
const targetSheet = targetSpreadsheet.getSheetByName(TARGET_SHEET_NAME);
//GETTING RESPONSES
var itemResponses = e.response.getItemResponses();
var responses = itemResponses.map(itemResponse => itemResponse.getResponse()); //Get responses
var name = responses.splice(0,1); //extracting first element ("Full Name") of responses
//GETTING SCORES
var itemScores = e.response.getGradableItemResponses();
var scores = itemScores.map(itemScore => itemScore.getScore()); // Get response score
scores.splice(0,1); //removing score for the first element ("Full Name")
var newArr = name.concat(scores); //combining name and scores in one array
//newArr.splice (1,0,""); //you can add this line to insert blank between "Student Name" and "Q1"
targetSheet.appendRow(newArr); //Append scores to the sheet
}
Test the script by submitting a form and the target sheet should show students names and the score for each question they answered. If you have any questions let me know.
