If you’re like most landscape architect candidates, you’re probably anxious to find out how many questions there are on the California Supplemental Exam (CSE) for landscape architects.
The official answer is 100 questions. However, many landscape architect who recently taken the exam I found a been answering more than 100 questions. What gives!
I decided to do a little research. The Candidate Guide published on LATC’s website dates back to 2013. In this candidate guide, it’s is that they’re only 100 questions on the exam. If this is the current guide, why are so many other landscape architects reporting that there are more than 100 questions on the exam?
I decided to reach out to LA TC and find out straight from the source.
In an email I received from a member of the Landscape Architect Technical Committee (LATC), they stated that there are only 100 questions which are graded on the CSE exam. But, they frequently test new questions to see what the responses. So, you may have more than 100 questions to ask but only 100 will be graded.
As you can understand, this is quite nerve-racking for somebody who’s prepared for a 100 question test and then his ass to answer more than 100. even worse, you don’t know which questions are going to be graded and which ones do not count.
Many landscape architect candidates have contacted me expressing dismay at questions that weren’t in the study guide or in the candidate guide. There’s a simple answer for this. These questions are for a future version of the exam and will not be counted on your exam.
As frustrating as it is, be prepared to answer more than 100 questions on the California supplemental exam for landscape architects. But remember, only 100 answers will count for you.
