AP US Govt & Poltiics: Texas Government Supplement

DS just received acceptance to COLA on 11/17 as a non auto-admit. Depending on how he performs on his senior year AP exams, it appears he will have about 30 hours of AP credits if he enrolls at UT. However, I saw this blurb respecting US Govt and Politics:

Eligibility for credit is based on AP scores combined with the UT Austin Test on Texas Government. Only students with a score of at least 3 on the AP exam are eligible to take the Texas Government supplement, but a score of at least 3 does not guarantee credit in GOV 310L.

Does anyone have insights into how or where DS could obtain a study guide or any similar resource to prepare for the Texas Government supplement?

UT Austin Test in Texas Government Only
Description:
The UT Austin Test in Texas Government is a required supplement to a score on the AP Government and Politics exam or the CLEP American Government exam. Before your eligibility for GOV 310L credit can be determined, you must arrange to take the UT Austin Test on Texas Government, which is offered only on the UT Austin campus. It is offered one time per month.

An official copy of your AP or CLEP score must be on file with Student Testing Services before you may take the UT Austin Test on Texas Government.

The twenty multiple-choice questions in this test cover the politics and government of the state of Texas. The questions are very similar to the questions in the CLEP exam in American Government. The subject matter of these items is devoted exclusively to Texas politics and government and includes questions on the following:

State government organization and powers
Political parties and elections
Social-economic environment
Constitution and local government
Policies, including state finance
Registration Fee:
When you confirm your registration to take the UT Austin Test on Texas Government, you will be immediately billed a non-refundable registration fee of $20.

Study Aids:
Although the test questions are not based on a specific textbook, the following Texas Politics webtext should be helpful in preparing for the examination:

@JAMCAFE, thank you so much for the substantive info.

I heard the test is full of really random questions and everyone receives the AP credit in the end despite not knowing the answers to anything, so don’t stress about it too much.
