Have you tried enabling the show response summary in end of survey within survey flow?
If not add an end of survey element at the end and click customize and override options and enable it.
Hope it helps!

Dear Deepak
Thank you SO much for your response, I truly appreciate it!
I have tried doing that and it works so far, but the challenge is that I should summarize questions into scales (e.g. questions 1-4 will be averaged for score 1; questions 5-15 to score 2, etc.) AND potentially add some qualitative evaluations/descriptions with it.
Would that be possible? I am guessing I'd have to write a script for that (I do have basic programming skills, just would need a description/the correct search terms to find such a tool that I could adapt).
Thank you so much!!

As far as averaging is concerned you can do it by assigning scores via Scoring Categories. You can do all kinds of Math Operations within Survey flow and would not need programming for it. For basic arithmetic programming (JavaScript Arithmetic (w3schools.com))
Once done you can use relevant embedded data to pipe in and show the evaluations.
Hope it helps!

Also, in case there is a different program/tool that allows for such personalization, I'd be very interested!
