Contest Structure

• 60 Multiple Choice Questions, which are divided into 20 of each topic Biology, Chemistry & Physics.

• Contestants are given 6 pts. for a correct answer, 0 pts. for unanswered questions, and lose 2 pts. for incorrect answers.

• The best possible answer is the correct answer.

Things to keep in mind …• The contest is hard!• However, the top scores at the State Contest

will be nearly perfect in each subject.• There needs to be a clear cut winner and this

will require a selection of hard questions on the contest.

• All schools divisions 1A – 6A compete with the same contest, but the scores are only compared with schools in the same division.

• But there are benefits for all of that effort spent in preparing for the contest…

9

Some Contest Rules• Contestants have up to 2 hours, but must

remain for at least 30 minutes.• You may use additional scratch paper

provided by the contest director.• Simple Scientific Calculators– Casio FX-260Solar

– Sharp EL-501X

– TI-30Xa

UIL Online Resources

• go to STEM > SCIENCE– Information from the Contest Directors will

be posted here.– The new Physics directed study

information is posted here.

28

Some Contest Strategies• Watch units!• Make diagrams with labels• Look for order of magnitude answers• Problem identification… • Quick/Easy, Moderate or Hard• -Use these identifiers to work on speed• -Recognize when to come back later

29

Coaches/Team Suggestions• Goal setting for student morale is very, very

important!• Have students solve old contests UIL or TMSCA

exams & help out other students.• Practice contests as posted on UIL invitational meet

site or attend TMSCA contests.• If possible coordinate with other teachers to

arrange for help when needed.• Positive reinforcement & food are good motivators.

Biology Contest Structure• Participants should expect questions from

all topics on all exams. • Approximately 75% of the UIL exam will

consist of questions from levels 1 and 2 and 25% of the UIL exam will draw from level 3 questions.

• The relative level of difficulty will increase with each contest.

QuestionsinChemistryInvitationals A & BTopics 1-11 (no 12 or 13) with emphasis on 1 and 2. Generally these 2 exams will have the easiest types of questions. Very straight forward information and calculations.

DistrictAll topics are possible (1-13) here. The questions will go a little deeper into the subject matter. Some problems will be complex in nature but overall, this is a notch down in difficulty from the regional and state exams.

Regional and State Once again, all topics will be covered (1-13). Any

40

The 20 questions in Physics:• There will be 3 directed study questions from“Astrophysics for People in a Hurry” by Tyson.

• Variety of question types: conceptual, symbolic, and numeric questions. Most will be numerical.

• There is a range of difficulty on each contest and over the contest season.

• Problems that require vector operations expressed in unit vector notation & calculus will be included on the state contest to help better differentiate the scores for the top students.
