QUALIFICATIONS

Every Credential Sighted and On File Before Dr Took a Brief

Degree-qualified in the subject they take.

PhD

Victoria University of Wellington · 2018

Testamur and full transcript sighted against photo ID in the same name.

Mass & energy balances

Confirmed and re-checked annually

Qualified while working professionally in the field before moving into academic support.

Timed subject test

Passed on entry · 2020

A past task sheet from a NZ paper, criteria sheet attached, clock running. First three orders second-read line by line.

Referencing sign-offs

APA 7th · Harvard

APA 7th tested on its own as the house standard, with Harvard signed off separately for papers that ask for it.

Technical areas they is signed off on

  • CAD and technical drawing conventions
  • NZS Standards referencing
  • NZ Building Code (NZBC) compliance
  • Structural and seismic design context
  • WorkSafe NZ requirements
  • Engineering calculation sign-off

What we do not claim

There is no accreditation body for academic writing, so nobody can hold one — including us. What can be checked is a degree, a professional membership and a test result, and those are the only things published here. How the whole panel is vetted sits on the our experts page.

EXPERIENCE

Thirteen Years: Practice First, Then the Marking Sheet

Time in the field before they ever tutored a NZ student. It shows in how the working is laid out.

  1. 2011 – 2017

    Early practice, Dunedin

    Building the professional grounding this desk now draws on — direct, hands-on work in the field before any teaching or academic support role.

  2. 2017 – 2019

    Professional practice continues

    Deepening specialisation in chemical & process engineering, the same area most of their briefs now sit in.

  3. 2017 – 2020

    Tutoring and academic support begins

    Where the pattern they now works to came from. Students were getting the right answer and still losing marks, because the method was never visible on the page.

  4. 2021 – now

    Chemical & Process Engineering desk, AssignmentHelpNZ

    164 student briefs across every NZ university and Level 5 to 7 diploma providers.

SERVICES

What Dr Take On, and What Comes Back

6 services cover almost everything that reaches this desk. Every figure is fixed in NZD before you pay.

Design reports

Calculations, assumptions and NZS Standards references laid out the way a marker checks them.

  • Assumptions stated before the calculation
  • Working shown at every step

FROM NZ$140

Lab reports

Method, results, discussion and error analysis structured to the faculty template.

  • Error analysis included, not skipped
  • Graphs formatted to convention

FROM NZ$120

Technical calculations

Structural, mechanical or electrical calculations worked with NZBC and NZS references.

  • Units and significant figures checked
  • Standard cited for every step

FROM NZ$115

Design and CAD review

Your own drawing set or calculation pack checked for compliance and clarity.

  • Compliance gaps flagged clearly
  • What you submit stays your own work

FROM NZ$45

Technical reports

A findings report structured the way an engineering examiner expects to read it.

  • Recommendation tied to the data
  • Appendices formatted to spec

FROM NZ$150

Project proposals

A scoped technical project written with budget, timeline and standards references.

  • Risk register included
  • Standards referenced throughout

FROM NZ$155

Included on every service

  • Full working shown line by line
  • Turnitin and AI reports attached
  • One free revision on the original brief
  • Fixed NZD price before you pay

What They will pass on

Pure programming assignments with no calculation component go to the programming desk. Business case studies on engineering firms go to the business desk. Dr does not take a brief outside their field, and you get that answer the same day rather than a late reallocation.

HOW THE WORK COMES BACK

4 Steps, in Order, on Every Brief They take

The same sequence whether it is one question or a full assignment.

1

Criteria sheet read first

They reads the marking rubric before the question, because that is what says where the marks are weighted.

2

Setup shown before any answer

The approach is named and the standard or framework it sits under is stated, so the method is visible from line one.

3

Working laid out step by step

Reasoning, working and answer on separate lines. One slip costs a step, not the whole question.

4

The answer interpreted

What the result means in context, in the sentence the rubric is waiting for. Reports attached with delivery.

Ask for Dr by Name. Find Out Tonight If They are Free.

Send the task sheet and the criteria sheet. Inside thirty minutes you get a yes or a straight no, a fixed NZD figure, and their read of what the question is actually testing. If they are booked, you get another engineering writer and the reason.

WHAT THEY HAVE ALREADY WORKED ON

Engineering Papers Students Have Sent to This Desk

Paper codes students named themselves. Most briefs run 1,500–2,500 words or an equivalent problem set.

Paper not listed?

Send the code and the task sheet anyway. Dr covers engineering across every NZ university and Level 5 to 7 diploma provider, and the table above is only what students have named publicly. If the paper turns out to sit with another specialist, you are told which one and why — see the full panel of verified writers.

REVIEWS, INCLUDING THE ONES THAT STING

What Students Said After the Marker Replied

Collected once results land, attached to Dr rather than the site, and the low ones stay up.

MK

M. K.

Bachelor

★★★★★

“The working was laid out step by step. I could follow it well enough to answer questions on it myself afterwards, which was the actual point.”

SR

S. R.

Master's

★★★★★

“Delivered ahead of the deadline with a clear explanation attached. I understood why the answer was right, not just what it was.”

TL

T. L.

Bachelor

★★★★☆

“Strong work and it was early. A couple of formatting details I had to fix myself, but the substance was solid throughout.”

AP

A. P.

Level 6 diploma

★★★★★

“I sent one question to see what it looked like. The approach was clear enough that I finished the rest of the set myself and got them right.”

JN

J. N.

Bachelor

★★★★★

“Caught an error in my own working that would have cost me real marks. That alone was worth it.”

HC

H. C.

Master's

★★★★☆

“Technically right and on time. One structural note I would have liked addressed sooner, but it was fixed on the revision without any fuss.”

Why they are collected late

A rating at checkout measures how the delivery felt. A rating after the marker replies measures whether the work held up. Dr's 4.8 is the second kind, which is also why it moves slowly.
