Demo – where a student lands in the app after signing up from a solution-bank page

Axi
Free account – unlimited asks
Maths › Edexcel C1 – Chapter 4 ‹ the exact topic they were stuck on
Restored from their ExamSolutions selection
the region the student lassoed on the solution-bank page

Exercise 4B – page 3
examsolutions.net solution bank

The signup deep link carried the topic and this pending ask. No generic dashboard, no hunting for where they were.

I am stuck on this part – can you explain the method?
Of course. Looking at the part you selected, the key move is to rewrite everything in the same form before you compare the two sides. Work through it one line at a time, and say which line stops making sense – I will take it from there. (In the live product, Axi answers from the actual lassoed region.)
Ask
Unlimited asks unlocked – the wall is gone, and the conversation continues right where the free asks left off.
How the deep link works: the conversion wall on the solution-bank page sends the student to /register?chat=1&topic=<topic-slug>&subject=Maths&next=<the-exact-solution-bank-url>. After signup the app opens this topic with the pending ask restored (selection crop plus exercise context), so the student continues the same question instead of landing on a generic dashboard.
