8th Grade Science Review

by Gabriel Luciano

Why is tomorrow's test important?

-You did NOT take the 8th grade Science STAAR.

-You also did NOT take the 8th grade Mock Science STAAR​

​

​-Because of this you will have to be pulled in to 30 hours of Science tutorials this year. UNLESS....... you can pass tomorrows screener,

​
