Overview
Engineering students are assessed on method as much as on answers. A marker wants to see the diagram, the assumptions, the governing equation, the substitution with units and a check that the result is physically sensible. Students who skip steps lose marks even with the right number, and cannot find their own errors when the number is wrong. Our tutoring builds that disciplined layout from the first session.
We cover core modules in mechanical, electrical, civil and chemical engineering, from first-year statics and circuit analysis to thermodynamics, fluid mechanics, structural analysis and reaction engineering. Sessions use worked examples that parallel your course problems and step-by-step review of calculations you have attempted.
Calculations we discuss are for learning and research. We do not provide certified engineering designs, stamped drawings or professional sign-off, and nothing in a tutoring session should be used as the sole basis for building, installing or operating anything.
Who it’s for and the problems it solves
This is for you if you are…
- First- and second-year engineering students struggling with statics, dynamics, circuits or thermodynamics
- Upper-year students in specialized modules such as heat transfer, control, geotechnics or process design
- Master's students returning to fundamentals for a design project or thesis
- Students from other countries adapting to different notation, sign conventions or unit systems
- Researchers who want an independent check of the calculation method behind a paper or thesis chapter
Common problems we help with
- You understand the lecture but freeze at the blank page of a new problem
- Your answers are off by factors of 1,000 or have the wrong units
- Sign conventions for moments, currents or heat flows keep reversing your results
- You are not sure which assumptions (steady state, ideal gas, small deflection) are justified
- Design questions ask you to choose a factor of safety or code value and you do not know how to justify it

How it works
Identify the module and gap
Share your syllabus, recent problems and where you get stuck. A short diagnostic problem shows whether the gap is physics, math or setup.
Model the method
We work a parallel example together, explaining each choice: boundary, diagram, assumptions and equations.
You solve, we question
You attempt a similar problem while we ask the questions an examiner would ask about your assumptions and units.
Review and consolidate
We review your written attempts, then give targeted practice on the recurring weak points.
How we structure an engineering calculation
- Given, find, diagram
- State the known quantities with units, what is required, and a labeled diagram: free-body, circuit, control volume or process flow.
- Explicit assumptions
- List simplifications such as steady state, negligible friction, rigid body, ideal gas or linear elastic material, and check afterwards whether results violate them.
- Dimensional analysis
- Carry units through every step and check each equation for dimensional homogeneity; use Buckingham Pi reasoning where scaling matters.
- Sanity checks
- Compare results with limiting cases, order-of-magnitude estimates and typical values for materials and systems.
- Sensitivity
- Vary uncertain inputs to see which ones matter, a habit that transfers directly to design and research.
- Computational checks
- Verify hand calculations with MATLAB, Python (NumPy, SymPy, Pint for units) or a spreadsheet, and explain any discrepancy.
Discipline by discipline
The four main branches share tools but differ in their core modeling habits. Knowing which habit a problem is testing helps you choose the method.
- Mechanical: isolating bodies and control volumes; energy and momentum balances
- Electrical: node voltages, loop currents and frequency-domain thinking
- Civil: load paths, equilibrium and compatibility, and how soil and water behave
- Chemical: conservation of mass and energy around process units, equilibrium and rates
Factors of safety and design codes
Design problems introduce factors of safety, load factors and material resistance factors. These come from design codes and standards (such as Eurocodes, ACI or AISC in structures, or ASME codes for pressure equipment), which vary by country and are updated periodically. We explain the logic behind them, how allowable stress design differs from limit state or load and resistance factor design, and how to cite the edition your course specifies. For real projects, the governing code and a licensed engineer's judgment always prevail.
Presenting calculations so they can be checked
A calculation that someone else can follow is more valuable than a correct final number. We coach you to present work in a consistent order, reference equations and data sources, round only at the end and state results with appropriate significant figures. This carries over into lab reports, design reports and theses.
What the work can look like
Illustrative example — fictional data
Sample calculation review comment: a beam deflection check
A second-year civil engineering student asked for review of a practice calculation for a simply supported steel beam. Values and comments are invented to show how feedback is written.
Units
The second moment of area was entered in cm⁴ while the elastic modulus was in GPa and the span in meters. Converting I to m⁴ (1 cm⁴ = 10⁻⁸ m⁴) brings the midspan deflection from an implausible 1.9 m to a plausible 19 mm.
Assumptions
The formula 5wL⁴/384EI assumes a uniformly distributed load, linear elastic behavior and small deflections. State these, and note that self-weight should be added to the imposed load if the question expects it.
Check against a limit
Compare the deflection with the serviceability limit your course uses (for example span/360) and state the comparison explicitly. This is educational practice only, not a design verification.
Illustrative example with invented numbers. Our feedback teaches method and does not constitute engineering approval of any design.
What you’ll need to provide
- Module name, syllabus or learning outcomes, and your textbook if known (for example Hibbeler, Çengel, Felder, Hayt)
- Past attempts, practice problems or tutorial sheets that show where you struggle

What affects price and turnaround
Price depends on
- Level and specialization of the module
- Number of topics and sessions needed before your exam or deadline
- Whether written worked-example sets or calculation reviews are included
- Use of specialized software or design codes
Turnaround depends on
- Time until your exam or submission and your availability for sessions
- Access to your syllabus, notation and required standards
- How much written review you want between sessions

Questions people ask before starting
Can you do my engineering homework or design project?
No. We teach the methods with parallel examples and review calculations you have done, explaining any errors. Graded homework, lab calculations, projects and exams remain your own work.
Can you check calculations for a real building or product?
We can explain methods and discuss a calculation for learning purposes, but we do not provide engineering certification, stamped drawings or approval. Anything that will be built, installed or operated must be designed and checked by a licensed or chartered engineer under the applicable codes.
Do you work in SI or US customary units?
Both. Many students struggle when a course or textbook switches between them, so we practice conversions and consistent unit handling explicitly, including slugs, lbf and psi versus kg, N and Pa.
Which textbooks and notation do you follow?
Yours. Sign conventions and notation vary between textbooks and instructors, especially for moments, heat flow and current direction. We adopt your course's convention so your notes and exam answers stay consistent.
I am doing a master's thesis with engineering calculations. Can you help?
Yes. We can review your calculation methods, assumptions and verification approach, explain theory you need and help you present calculations clearly in your thesis. Interpretation and write-up remain yours, and you should acknowledge assistance as your institution requires.
