This guide introduces three practical tools people use every day: a Time Calculator, a BMI Calculator, and an RBT Practice Exam. Each tool serves a different purpose, but all help users make faster, more informed decisions. Use the table of contents below to jump to what you need.
1. Time Calculator
The Time Calculator helps you add, subtract, and convert time values without manual math. It is especially useful for scheduling, timesheets, travel planning, and productivity tracking.
What it does
- Adds or subtracts hours, minutes, and seconds
- Converts time between formats (e.g., hours to minutes)
- Helps calculate total work or project hours
Why it’s useful
It removes calculation errors and saves time when handling multiple time entries or comparing time intervals.
2. BMI Calculator
The BMI Calculator (Body Mass Index Calculator) estimates body fat based on height and weight. Health professionals commonly use BMI as a quick screening tool.
What it does
- Calculates BMI using the standard formula
- Categorizes results (Underweight, Normal, Overweight, Obese)
- Gives a general picture of weight-related health risk
Why it’s useful
It provides fast, easy insight into weight status. While BMI is not a full health assessment, it helps users understand where they stand and when to seek more personalized guidance.
3. RBT Practice Exam
The RBT Practice Exam helps future Registered Behavior Technicians prepare for the official credentialing test administered by the BACB.
What it does
- Tests knowledge of ABA (Applied Behavior Analysis) principles
- Covers required competency areas such as measurement, assessment, skill acquisition, and behavior reduction
- Builds confidence before taking the real exam
Why it’s useful
Consistent practice improves understanding of ABA concepts and helps candidates identify areas that need more study before certification.
