Sat scores significantly lower than practice tests

The sat cores for subject and general sat are like 250 points lower in the real test when compared to those taken at home and at testing centers. Anybody encountered this issue? Any advice? Thanks

Same thing here. When I was taking practice tests I was scoring 34 and I got a 32 on the actual one. I’m sitting for it again in fall and I think the reason I didn’t do so well was because I let the pressure of it being the real test get into my head. I would just try to relax during test day, get a good night’s sleep, and pretend like it’s just another practice test.

Where are you taking practice tests from? I tossed my Princeton Math 2 book once it gave me consistent 800s, yet I got a 770 on the real test.
