How hard are Paper 1 coding challenges ? ( Previous A-Level CS students help)

How hard are Paper 1 coding challenges ? ( Previous A-Level CS students help)

Kian2005

Wondering for anyone who has sat A-level comp sci in previous years, how hard are the coding challenges? We have a resource called ZigZag and the coding challenges are very hard. Is this the level they are in the actual exam? Are instructions clear in the exam (those on zigzag are not particularly clear)?
