Good Luck Strikes on Exam Day, But Only for a Limited Time

Introduction:

I'm Ruan Yi, and my senior-year class-placement exam is coming up.

My mom said if I don't get into the top class, she'll confiscate my phone.

I've prepared myself for life without my phone.

Then, during the exam, a notification sound suddenly startled me and made me happy:

[Exam Ace System binding in progress. Get the standard answers in one tap.]

[Hello, Host Ruan Yi. Your gold-medal tutor is at your service. You can call me Chick.]

Me: ?

[Ahem. Chick, present the answers to me at once.]

Suddenly, a sky screen appeared before me like a dropdown menu...

ADACB, BDCAD...
