Which mock exams are most representative?

I took 6 schweser mock exams and also the CFAI mock exam…my scores continued to improve as I progressed and I was feeling relatively confident, but now I am reading others posting about the testrac exams which I am not too familiar with and everyone’s moments are making me feel nervous.

From past experience does anyone know which kick exams are most representative of the real exam so that I could hopefully feel confident and not discouraged after everyone writing how they were doing well until taking these testrac exams
