I need to create a survey form to collect feedback from students about teachers' performance.

I have a contact list that consists of student IDs and email addresses (for authentication). This contact list also includes the corresponding teacher IDs for the classes the students attend (one student will map to more than 80 teachers). e.g. StudentID(ExternalReference), Email, TID001, TID002…, TID080

In the supplemental data, I have teacher IDs, teacher names and their corresponding class information (e.g., date, course ID, course description).

Requirements:

1) Dynamically populate the teacher information according to student logins, along with a Likert scale question and a comment box. xCurrently, I map TID001 (in contact list) with TID (in supplemental data) to display teacher and course information above the survey question in each block]

2) Include a back button in each block (*however, I found that there will be no back button if I use logic for blocks).

3) Add a table of contents/or other means so that students can jump to the particular teacher to fill in the evaluation form. (*it seems impossible when I use logic and embedded data)

Does anyone have an idea of how I can achieve this? Thanks.
