What every option still needs from you
- The books. It is open book, and the test center supplies no references. Whatever else you buy, you still need the listed titles, in allowed editions, tabbed. See the reference books guide and how to tab your NASCLA books.
- Lookup speed. About 2.6 minutes per question includes the lookups. See how to pace 125 questions in 330 minutes.
- Your state's steps. No study option changes what your state requires beyond the trade exam. See NASCLA exam vs a state trade exam.
What to check before you pay anyone
- Is it written to the twelve subject areas? Procurement and Contracting Requirements (31 questions) and General Requirements (25) are almost half the exam. Good prep weights its practice the same way. The exam outline has the counts.
- Does it teach where to look? On an open-book exam, an explanation should name the listed book and topic so you can find it in your own copy.
- Is the content original? Never buy anything promising real or recalled exam questions. Candidates may not copy or share exam content, and the bulletin says doing so breaks the candidate's agreement with PSI and the law.
- Which code editions does it use? IBC 2021 or 2024 and ACI 318-14 or 318-19 are the listed choices. Prep that teaches another edition can teach you the wrong number.
- What renews, and what is the refund rule? Read both before you pay.
- Does it score by subject area? A single percentage hides where your points are.
A practice score is not a prediction
No practice score, ours or anyone's, predicts your exam result. Use your score to decide what to study next.
Take the free 10-question check first. You see your score by subject area without signing up, so you know what kind of help you need before you pay for any of it.
What you get from Bid Bond
The NASCLA Commercial course has a lesson for each of the 12 subject areas that shows which listed reference to open and how to apply it, original practice questions with every answer worked, and four timed practice exams of 115 questions on a 330-minute clock. Your scores come back by subject area, so you know where the next study hour goes. It does not replace the books: you still bring your own. The price and refund rules are on the course page. See the course.
Common questions
Do I need a class to pass?
No study format is required. The exam needs the subject knowledge and fast lookups in your own books; how you build them is up to you.
Can I use an online course instead of the books?
No. The exam is open book with references you bring, so you need the listed titles whatever else you use.
Does Bid Bond promise I will pass?
No. Nobody can promise you a pass.
