Does ordering extra tests on CCS get penalised on actual exam?

CCS cases doesn’t penalise for ordering extra non invasive tests like a couple extra blood tests/ X-rays etc But do we get penalised for it on the actual exam? I find myself erring on the side of ordering a few extra tests on CCS to avoid missing out on points because the software doesn’t penalise for it. Just wanna make sure if the same applies for test day.

I have my exam soon, help would be appreciated!
