I am taking it in California. Here is what the requirements say.
"REFERENCE MATERIALS – There are two types of documents that apply: professionally, published reference materials that are bound by staples and reference materials that are manually or hand stapled. The published reference materials that are securely fastened in their covers by their staples are allowed. Manually or hand stapled documents and are NOT securely fastened in their covers are NOT allowed. “Post-Its” will be permitted as book tabs only (must be attached prior to entering the testing area). You are permitted to bring as many reference materials into the testing area as one trip will permit. Fire Codes require that all aisle ways be kept clear.
All reference materials (i.e. including all forms of notes) must be bound and remain bound during the exam. “Bound” refers to material permanently bound by stitching or glue and materials fastened securely in its cover by fasteners which penetrate all papers (i.e., ring binders, spiral binders, plastic snap binders, brads, or screw posts). Published reference materials entitled, “120 Solved Surveying Problems” for the California Special Civil Engineers 10-10_PE_PS Examinee Instructions, 10/01/10 3
Examination (CSSP) and “Civil Surveying Samples Examinations” for the California Special Engineering Surveying Examination (CSSE2) will be allowed."
So from that it seems as if personal notes in a three-ring binder should be allowed.
