- Fractions (this worksheet helps teach and reinforce concepts necessary to perform simple arithmetic with fractions.)
- Fundamental principles of algebra (this worksheet helps teach and reinforce concepts necessary to manipulate and substitute algebraic equations.)
- Applications of trigonometry (this worksheet helps teach and reinforce concepts necessary to apply right-triangle trigonometry to the solution of practical problems.)
- Calculus concepts and applications (this worksheet helps teach and reinforce concepts related to differentiation and integration, mostly qualitative and numerical as opposed to symbolic.)

- Unit conversion problems
- Work, energy, and power
- Simple machines
- Static fluids
- Dynamic fluids
- Elementary thermodynamics
- Molecular quantities
- Balancing chemical reaction equations (stoichiometry)

- DC circuit calculations
- Transformer circuit calculations
- AC reactive circuit calculations
- Process switches and switch circuits
- Process switches and PLC circuits (this worksheet helps teach and reinforce concepts of normally-open and normally-closed contacts, both real and virtual, and how their statuses relate to each other. This happens to be one of the more challenging concepts to master when learning PLC ladder-diagram programming.)
- Pictorial circuit diagrams (this worksheet helps teach and reinforce concepts of wiring components together that are not drawn in neat, organized, schematic form -- an essential concept to master for performing actual device wiring on the job!)
- Fault analysis of simple circuits (this worksheet helps teach how to assess the likelihood of different faults in simple electrical circuits -- an essential concept to master for performing troubleshooting on the job!)
- Three-phase AC circuits (this worksheet helps teach how to calculate voltage, current, and power quantities in three-phase AC circuits)

- Reading analog scales (this worksheet helps teach and reinforce concepts related to the interpretation of analog meter and gauge faces.)
- Instrument calibration tables (includes analog-digital conversion tables)
- Troubleshooting problems in control systems (this worksheet helps teach how to diagnose problems in control systems based on operator reports and observed behaviors -- an essential concept to master for performing troubleshooting on the job!)
- Pumps and compressors (this worksheet explores the physics of pumps and compressors, as well as auxiliary equipment and controls to keep them operating safe and efficiently)
- Liquid level measurement using hydrostatic pressure and buoyancy (this worksheet helps teach how to calculate level-measuring instrument ranges)
- RTD and thermocouple circuits, with millivolt calculations (this worksheet helps teach how to calculate millivoltage values within RTD and thermocouple circuits)
- Pressure-based flowmeter calculations (this worksheet helps teach how to calculate values such as differential pressures versus flow rates)
- PID loop tuning (this worksheet helps teach how to analyze process control trend graphs to identify loop control problems)

While not a practice-problem worksheet in the strictest sense, this worksheet nevertheless contains a set of useful P\&ID and loop diagrams drawn with industry-realistic levels of detail. These are helpful for students wishing to gain more experience interpreting and drawing such diagrams, as well as instructors who might wish to take these diagrams and use them as the basis for homework or exam questions.

As with all the diagrams in the Socratic Instrumentation project, these graphic images are vector-based, not raster, and as such may be magnified without pixellation.

Mastery exams are administered repeatedly throughout the second year of the Instrumentation program to ensure learning on a variety of essential topics. A 100% (perfect) score is necessary to pass. Failure to attain 100% correctness on a mastery exam results in re-taking another version of the mastery exam in its entirety. There is no grade penalty for any number of re-takes, but the student *must* pass the mastery exam by a specified deadline date in order to pass the course.

The way a mastery exam is administered is like this: the student takes the exam, presents it live to the instructor, who then grades it against an answer sheet (see the last page, not printed for students). If 100% of the answers are correct, the student passes the exam. If any answers are incorrect and/or if any work is not shown, the instuctor then marks which section(s) of the exam contain mistakes on the table at the top of the cover page and hands the exam back to the student, who now has one more chance to review their work and correct any errors. No hints whatsoever are given to the student regarding the mistakes or omissions. If upon the student's second submission all answers are 100% correct, the student passes the exam. If, however, any old mistakes remain and/or any new mistakes have been made, the student then must meet with the instructor to determine where they went wrong, what they should practice or study more, and when the re-test will be (with a different version of the exam).

The following links provide samples of a mastery exam designed to test knowledge on a variety of first-year (basic electricity and electronics) concepts:

These are multiple-choice exams written in the same style as popular certification exams, designed to cover most of what a typical two-year program in Instrumentation would teach. Admittedly, these ``certification prep'' exams are not as rigorous as typical exams given in the Instrumentation program, but they are good practice for employment entrance exams and industry-recognized certification exams, which sadly tend to focus more on rote memorization and recognition rather than actual problem-solving skill. I no longer give this exam as practice to my students, and so the answers to all questions are provided on the last several pages of each exam so that you may check your own performance:
