Algebra 1 Honors Final Exam

REVIEW June 2015

Name: Period: Your final examination will consist of 52 multiple-choice questions worth one point each

which will be completed on a Scantron form. The exam will include material from the

following units: Exponents, Polynomials, Factoring, Radicals, Quadratics, Compound

Inequalities, Absolute Value Equations and Inequalities

NOTE: School policy mandates a penalty for cheating on an exam to be a grade of

ZERO for that exam. The term cheating includes "intent to cheat." NO CELL

PHONES. All cell phones must be kept out of sight. If a cell phone is seen during

an exam, you will receive a grade of ZERO.

All calculators may be checked for inclusion of extraneous material. No papers

should be placed in calculators. No information should be written on the

front/back of calculators. The program portion of the graphing calculator will be

checked. Any information entered there can be considered intent of cheating.

Before the examination, clear your calculator of any formulas, notes or any such items, which

could be perceived as "useful" or providing unfair advantage. The best solution is to RESET

and clear the memory completely.

The following pages provide a comprehensive review of the materials to be studied for this

exam. We will take a few days of class time to review for this exam. Please feel free to stop

in on your own time for further assistance. Good Luck!
