You need to be familiar with Building Codes and Federal laws and regulations that impact your building. Fortunately these are all online for free.

2021 INTERNATIONAL BUILDING CODE (2021 IBC)

Link: 2021 International Building Code
Comment: Focus on chapters 3, 4, 5, 6, 7, 9, 10 and 11
Additional Info: I have a few IBC blogs on this site. For more info you can read the following posts. How to Round Code Requirements, Gross Floor Area Explained and 10 Things to Know About the International Building Code

2010 ADA STANDARDS FOR ACCESSIBLE DESIGN (2010 ADAAG)

Link: 2010 Standards for Accessible Design
Note: For ARE 5.0 exams, remember that the ADA is a Federal LAW, not a building code. Chapters 3, 4 and 5 will take you far.

FEMA 454: DESIGNING FOR EARTHQUAKES: A MANUAL FOR ARCHITECTS (FEMA 454)

Link: FEMA 454: Designing for Earthquakes: A Manual for Architects
Comment: An absolute must-read for PPC and PDD. Focus on Chapters 4 and 5.

You will need to know these in detail for Practice Management, Project Management and Construction and Evaluation.

AIA CONTRACT DOCUMENTS

Link: https://hyperfinearchitecture.com/AIAContracts
Comment: Start at the home page, then navigate through the different series. Where available, the ARE 5.0 exams use the 2017 AIA Contracts. A201 is a must read. Also check out A101 and B101. The full list of contracts you need to know is at the end of the NCARB ARE 5.0 Handbook.

I am a big believer in studying direct from the primary resources. The best way to learn the contracts is to read the real thing! If you need some help finding and focusing on the most important topics, check out my PcM and PjM Study Course. It has 7 contract-specific study assignments with over 50 questions.

AIA CONTRACT DOCUMENTS COMMENTARY

Links:
AIA A201: General Conditions for Construction with Commentary
AIA B101: Owner-Architect Agreement with Commentary

Comment: These are the full contracts, with the plain language commentary to better explain each section. Note that these are for the 2007 version, though they are still incredibly helpful. Use the search bar to search “commentary” to find other contracts.

SCHIFF HARDIN LECTURES

Link: Schiff Hardin Lectures

Comment: This audio lecture is also known as the Hanahan lectures. The recordings are from the professional practice course at the University of Illinois at Chicago, taught by Michael Hanahan. He is a lawyer, formerly at the firm Schiff-Hardin. Schiff-Hardin had previously hosted all the lecture notes and audio recordings on their site. Hanahan left the firm in 2019, and his lectures were removed from the site. The Spring 2019 lecture can still be found on archive.org, as linked above.

PLURALSIGHT

You may have heard of Kevin Griendling. His video series is hosted on Pluralsight. This is a paid resource, though you can get a free 10-day trial. It's about $30/month after that, so a good budget option when compared to Black Spectacles

There is a large, and growing, community of people going through the same thing you are, and sharing their experience and knowledge.

JENNY'S NOTES

THE ARE FACEBOOK GROUP BY YOUNG ARCHITECT

Link: https://www.facebook.com/groups/architectregistrationexam/

I don't know of any completely free practice quizzes, but nearly all the paid sites offer free samples.

DESIGNER HACKS

Link: ARE PcM: Exam Prep, Quiz & Resources
