Google form page route

Hi

Here is what i am looking for.... I have a Google form with 7 sections, namely

section 1 . Subjects (what subject do you teach? a list of 2 subjects)

section 2 . Topic (select a topic.. the topics of the subject 1)

section 3 . Topic (select a topic.. the topics of the subject 2)

section 4 . Sub-topic (select a sub-topic ... subject 1, sub-topics of topic 1)

section 5 . Sub-topic (select a sub-topic ... subject 1, sub-topics of topic 2)

section 6 . Sub-topic (select a sub-topic ... subject 2, sub-topics of topic 1)

section 7 . Sub-topic (select a sub-topic ... subject 2, sub-topics of topic 2)

Based on the selection, you are taken to the respective section. What i want is to show ur path as you move on. May be something like this

 Subject > Topic > Sub-topic
 Computer > Software > OS
 Biology > Plants > Photosynthesis
 Biology > living things > Digestion

I am OK if this path can be shown in last page/section

How can i do this..I think I have read all relevant link... pls guide me if the solution already exists..
