Study Guide for 8th grade final – Semester one

8th Grade Science
Semester 1 Final Review

The first semester final will be comprehensive from the beginning of the year until now. The format for the final is the same as it has been for all tests:
Multiple choice (about 30 questions)
Short Answer (about 15 questions)
Science/Math problems (about 15 questions)

Approximately 60 questions worth a total of about 100 points.

The final exam will count as two test grades and will be worth approximately 100 points. This will be the last graded material from the first semester.
