What is what calculator can i use on the fe exam?
When preparing for the Fundamentals of Engineering (FE) exam, understanding **what calculator can i use on the fe exam** is arguably as critical as knowing the Rankin cycle or beam deflection formulas. The NCEES (National Council of Examiners for Engineering and Surveying) maintains a very strict policy regarding electronic devices to ensure exam integrity and fairness.
Every examinee must use a calculator from the approved list. If you bring a device that is not on this list, it will be confiscated, and you may be barred from the testing center. Candidates should use our selection tool early in their study process to ensure they are familiar with the specific keybindings and functions of an approved device. A common misconception is that any “non-programmable” calculator is allowed; however, NCEES specifically names approved series, and anything outside those brand-model lineages is strictly prohibited.
what calculator can i use on the fe exam Formula and Logical Explanation
The “formula” for determining **what calculator can i use on the fe exam** is not a mathematical equation, but a logic-based filtering process based on NCEES Rule 1.40. The primary criteria include the absence of communication capabilities (Wi-Fi/Bluetooth), no external memory storage, and no QWERTY keyboards.
| Variable | Requirement | Threshold | Typical Impact |
|---|---|---|---|
| Programmability | Zero | No User Stored Text | Prevents cheating via stored formulas. |
| Communication | None | No IR/RF/Wireless | Ensures isolated testing environment. |
| Model Name | Exact Match | Series specific | Determines center entry. |
Practical Examples (Real-World Use Cases)
Example 1: The Civil Engineering Student
A student preparing for the Civil FE exam needs to solve 3×3 matrices for structural analysis. By asking **what calculator can i use on the fe exam**, they discover the TI-36X Pro allows for matrix entry. They purchase it 3 months before the exam to practice simultaneous equation solving, shaving 15 minutes off their exam time.
Example 2: The Mechanical Engineering Professional
An EIT (Engineer-in-Training) candidate prefers the Casio ecosystem. They check the NCEES list for **what calculator can i use on the fe exam** and find the Casio fx-115ES PLUS is allowed. They utilize the built-in unit conversion features to quickly move between Metric and Imperial units during the thermodynamics portion of the test.
How to Use This what calculator can i use on the fe exam Calculator
- Select your preferred brand: Casio, TI, or HP. If you have no preference, leave it on “Any”.
- Choose “Advanced” if your discipline requires complex number math or vector calculus.
- Adjust the “Budget” slider. Note that the HP 35s is significantly more expensive than the TI or Casio alternatives.
- Read the “Key Benefit” section to understand why that specific model fits your input.
- Use the “Copy Results” button to save the model name for your next Amazon or Staples trip.
Key Factors That Affect what calculator can i use on the fe exam Results
- Screen Readability: Multi-line displays allow you to verify your input before hitting enter, reducing simple arithmetic errors.
- Power Source: Solar-powered models (like the TI-36X Pro) are preferred to ensure the battery doesn’t die mid-exam.
- Tactile Feedback: The HP 35s is famous for its clicky keys, which some engineers prefer for speed and accuracy.
- Functional Depth: Does the model handle numerical integration? Most approved Casio and TI “Pro” models do.
- Cost vs. Value: Most FE-approved calculators range from $15 to $70. The investment is small compared to the exam fee.
- Learning Curve: If you used TI in high school, staying with Texas Instruments for the FE exam reduces cognitive load.
Frequently Asked Questions (FAQ)
Can I bring two calculators to the FE exam?
Yes, as long as both models are on the approved NCEES list. Many candidates bring a backup TI-30X in case their primary TI-36X Pro fails.
Is the TI-84 or TI-Nspire allowed?
Absolutely not. Graphing calculators are strictly prohibited because they can store text and have communication capabilities.
What happens if my calculator is not on the list?
The proctor will ask you to place it in a locker. You will have to do the entire exam using the on-screen digital calculator provided within the CBT interface.
Does the Casio fx-991EX work for the FE exam?
Yes, the fx-991 series is explicitly listed by NCEES and is a top-tier choice for the exam.
Are there any HP calculators allowed besides the 33s and 35s?
No, only the HP 33s and HP 35s models are permitted. No other Hewlett Packard models meet the criteria.
Does the calculator need to be “Calculus Capable”?
While not strictly required, having a calculator that can perform definite integrals and derivatives (like the TI-36X Pro) is a massive advantage.
Are covers allowed in the testing room?
Usually, you must remove the plastic slide-on cover and leave it in your locker before entering the testing room.
Is it worth buying an HP 35s?
If you are a fan of RPN (Reverse Polish Notation), the HP 35s is the only RPN-capable calculator approved for the exam.
