is this a suspicious increase in score?

hey guys so i solved practice test 7 on bluebook 2 days ago and i got a 1050 and rn i just solved practicet test 6 and i got a 1220 my math score increased alot cuz i crammed some videos but still feels weird my exam is tomorrow would 1220 indicate my real score with like -10 or +10 marks or should i take another practice test?
