Every concept, from the origin. Every student, one-on-one.
Personalised maths tuition in Porvorim and online with Dominic Desa. We find exactly where your child's understanding breaks down, rebuild it from the ground up, and prepare them for their board exam, one student at a time.
↳ demo class is free when you enrol.
A class of forty moves at one speed. Your child shouldn't have to.
Most students who "aren't good at maths" missed one building block a year or two ago. Big coaching batches never go back for it. We do.
Typical coaching class
- 30–60 students, one pace for everyone
- Doubts wait until after class, or never get asked
- Same notes for every board
- Parents hear about problems at exam results
- Fixed batch timings and travel time
Origin 360°
- One student, one tutor, a plan built around their gaps
- Doubts answered in class, and on WhatsApp between classes
- Board-specific preparation and past-paper practice
- Clear practice instructions for parents when a topic needs work
- Timings that fit your week, at home or online
Five boards. Five different exams. One tutor who knows each.
Each board tests maths differently. Preparation is matched to your child's syllabus, textbook and paper pattern.
IGCSE Mathematics
Cambridge IGCSE rewards clear working and problem-solving across unfamiliar contexts. We prepare students for the right tier and build the habit of showing method marks, with plenty of past-paper practice under timed conditions.
Focus areas
- Choosing Core vs Extended with confidence
- Calculator and non-calculator technique
- Functions, vectors, transformations
- Topic-wise past papers and mark schemes
ICSE Mathematics
ICSE maths is lengthy and detailed, and speed matters as much as accuracy. We work through the textbook exercises thoroughly, then train for Section A and Section B so students finish the paper with time to check.
Focus areas
- Commercial maths: GST, banking, shares
- Matrices, coordinate geometry, loci
- Constructions and geometry proofs
- Speed drills for long-form papers
CBSE Mathematics
NCERT is the foundation, but today's CBSE papers lean heavily on case-based and competency-based questions. We master every NCERT exercise and example, then go beyond with the newer question formats.
Focus areas
- Complete NCERT coverage, chapter by chapter
- Case-based and assertion–reason practice
- Trigonometry, statistics and probability
- Sample papers and previous years' papers
SSC Mathematics
Goa Board students sit the SSC exam in Class 10, set by the Goa Board of Secondary & Higher Secondary Education. We work through the prescribed textbook chapter by chapter, then drill the question types that repeat in board papers year after year.
Focus areas
- Linear equations, quadratics, progressions
- Similarity, Pythagoras, circles, constructions
- Theorem proofs written for full marks
- Previous years' board paper practice
NIOS Mathematics
NIOS students study on a flexible schedule, which makes structured guidance even more important. We set a clear plan, help with assignments, and get students exam-ready for their chosen session.
Focus areas
- Study plan matched to the exam session
- Tutor-marked assignment guidance
- Building confidence after a break from school
- Previous question paper practice
Four quadrants. One full circle.
Every student moves through the same loop, at their own pace, until the topic is fully understood.
Diagnose
A relaxed first session to find where understanding actually breaks down, not just which chapter is next.
Build
Rebuild concepts from the origin, with visuals and real reasoning instead of memorised steps.
Practise
Graded practice from textbook to board-level, then timed past papers in the exam's real format.
Review
Regular check-ins in class, with practice instructions for parents when a topic needs more work. Weak spots go back into the loop until they're strong.
From foundations to the board exam.
The exact chapters depend on your board. Here's the ground we cover across grades.
Foundation years
Where most future gaps begin. We make sure they don't.
Board exam years
Full syllabus coverage plus exam technique, papers and revision.
Hi, I'm Dominic.
"No child is bad at maths. They've usually just been rushed past the origin."
I trained as an architect, with a Bachelor of Architecture from Goa College of Architecture. Architecture runs on geometry, proportion and logic, and it taught me to see maths as something you build, one solid layer at a time.
I started Origin 360 in October 2025 to teach maths that way: one student at a time, starting from what they already know and building outward until every angle of a topic makes sense. Today I teach 13 students, and I'm proud that their grades have climbed a notch every semester.
I teach Grades 7 to 10 across IGCSE, ICSE, CBSE, SSC and NIOS, at students' homes in Goa and online over Google Meet. Whether your child is aiming for a top score or just wants to stop dreading maths, we'll get there together.
Built around your child's week.
Practice guidance
When a concept needs reinforcing, you'll get clear instructions on what to practise at home.
WhatsApp doubt support
Stuck on homework? Send a photo of the problem from a parent's WhatsApp and get help between classes.
Flexible scheduling

Frequently asked.
Is the demo class free?
It's free if you go ahead with classes. The demo is a full session where Dominic gets to know your child's level and you see how classes work. If you decide not to continue, there's a small charge to cover travel and time.
Which grades and boards do you teach?
Grades 7 to 10, across IGCSE (Cambridge), ICSE, CBSE, Goa Board SSC and NIOS.
Which areas do you cover for home tuition?
Home classes are within about 5 km of Porvorim, and in some cases up to 10 km. If you're further away, live online classes on Google Meet work just as well.
Do you offer group or batch classes?
Classes are 1-on-1 so every session is built around your child. If siblings or close friends want to study together, just ask.
How do online classes work?
Classes run live on Google Meet, so your child can see every step and ask questions as they go. All you need is a laptop or tablet and a stable internet connection.
How many classes a week, and what are the fees?
Most students take two to three classes a week, each 1 to 1½ hours depending on age and attention span. Extra slots are available when the schedule allows. Fees are shared on request: message on WhatsApp.
My child is already in Grade 10. Is it too late?
Not at all. Board-year students get a focused plan that prioritises high-weightage chapters, fixes the most costly gaps first, and builds in timed paper practice before the exam.
