How to Answer a Section C question in 36 mins or less?

When I look at my BPP kit, particularly in the Section C parts, I always see “36 mins” on the right. I figured that should be the amount of time to answer a single section C question. But I always find myself answering it for more than 36 mins, especially on creating financial statements.

When I usually approach Sec C questions, I read the requirements first and link it to relevant info, then start solving?

So is there any tips to speed up my solving?
