My personal experience is 七宗罪+黄金80题=5.5, but you need to make some modifications to 七宗罪 in your own style. otherwise not easy to remember...you can't memerize everything in the real test!
Just practise high frequency topics in 黄金80题 is more than enough. On my test day I met both of my AA and AI from 黄金80题.
