Illustrative solutions for past exam

Dear sir,

Illustrative solutions for specimen exam 1 which is issued by Opentuiion is very helpful for me.
It helps me to know how to write a short sentence but contain enough content to gain mark.

Answer by examiner is also helpful but it is very long, and it is difficult to define how many points needed.

Will Opentuion issue more illustrative solutions for other past exams? I think many students also like that.

Thanks.
