For section LA4, section B, just answer the part b) on Human Rights, there's been one every paper so far. That was it isn't really synoptic, its just this year's material.
If that fails, just hope that your LA3 revision will contribute to your part b). What topics have you revised so far?
For the HRA evaluation, literally describe the law and evaluate whether or not it's helpful or not, such as evaluate S4 with S10? Have you looked at Bill of Rights? That helps with evaluation too!
