Designed course that grew revenue 4.7× at Nata Ace
Client: Nata Ace Tutorial was an early-stage test prep startup for NATA, India's national architecture entrance exam. Think of it as the SAT for architecture school, except it also tests drawing and spatial aptitude. The business ran as a classroom operation in one Mumbai suburb, with 20 students per batch.

(Overview)
The course worked. The business couldn't scale it. Nata Ace could teach only 20 students at a time because everything depended on a classroom and a teacher being physically present. One full batch generated $19,200 at $960 per student. I designed the company's first online course so the teaching could be produced once and delivered repeatedly without a teacher in the room. In its first online year, 500 students paid $180 each, generating $90K in course sales.

Source: First online cohort course data.
Before: 20 students per batch, one classroom, $19.2K per batch.
After: 500 paying online students in the first year, $90K in course sales. The online course was priced at $180 per student, 81% lower than the classroom course.
Let's break down the problem
(Problem 1)
The business was capped by the classroom.
Nata Ace could only sell 20 seats at a time. Every new student required another classroom seat, another batch, and more teacher time. At $960 per student, one full batch generated $19,200. To grow, the company needed a product that could be sold without adding another room.
But scale alone wasn't enough. Students outside Mumbai also needed a course they could actually follow independently, without a teacher beside them.
"I don't know what comes next, so I just watch a few posts and then leave." Class 12.
(Problem 2)
Recording the class would not have worked.
The business needed to produce the course once & sell it repeatedly. A recording wouldn't solve that. In the classroom, I decided what came first, when to slow down, & when to make someone redraw something. Online, those decisions had to become part of the product.
The sequence, pacing, and feedback a teacher provided live had to be designed into the course once, so hundreds of students could use it without hundreds of teacher interactions.
The exam covered 37 topics, and nothing online put them in a useful order. Sequence, pacing, and feedback were the product. The slides were just where they showed up.
(Process 1)
Three years in the room, then the interviews
I had taught NATA for three years, so I didn't start by discovering pain points. I started by checking which of my classroom assumptions held outside it. Students in smaller cities consistently pointed to three gaps: no clear starting point, no feedback on practice work, and material written for students at expensive coaching centers.
Our content audit added the structural problems: inconsistent naming, no hierarchy, and no progression signal. The opportunity wasn't to digitize the classroom. It was to design a course that could work without one.
Student interviews and observations across non-metro classrooms.
6 months of production down to under 2, which is how two people shipped 111 pieces.
(Process 2)
Architecture before any visual work
I mapped 37 topics across 10 modules using the same six-phase structure, creating 111 content pieces across three formats.
I tested the structure with students before visual design, then used ChatGPT to speed up drafting and iteration. The repeatable system cut the projected build from six months to under two, with 40% fewer iteration cycles.
(User Goals)
As a student with no test prep center near me, I want a course I can afford and follow on my own, so my preparation is not decided by my zip code.
NATA Aspirant, small city
As a two person company, I want to produce the course once and sell it anywhere, so growth is not capped by a room.

(Iterations)
1. The lecture, moved onto slides 🚫
The obvious first move, and what every competitor had done. It reads fine to a teacher, because the teacher paces it live. On a phone at 11pm it is an info dump. A student cannot tell what she is meant to remember, and nothing in it says where she is.
2. Split by topic, still no shape 🚫
Breaking the lecture into topics fixed the length but not the experience. Each topic still carried a different structure, forcing students to learn the format before the concept.
3. Six phases, every topic ✅
Context, concept, application, refinement, independent practice, extension. Same order, same slots, all 37 topics.
Version one had no shape. Version two had a different shape each time. What fixed it was one rule: each step does a single job, and nothing is introduced before the student can use it.
That rule is also what made the structure repeatable, which mattered at 37 topics and 111 pieces.
(Learnings)
1. Knowing your users already is not a substitute for research. Three years of teaching told me where students struggled. The interviews told me why: they didn't just need more content. They needed structure, progression, and feedback they could access on their own.
2. Scalability is a design problem, not just a distribution problem. Putting a classroom course online would have increased distribution, but not necessarily made it usable without a teacher. The scalable part came from designing sequence, feedback, progression, and production rules into the course itself.
(Solution 1)
1. A list of topics became a course
The business needed a course that could guide hundreds of students without hundreds of teacher interactions. Sequencing gave students a clear next step. Progress markers showed them where they were. Refinement and practice turned worked examples and common mistakes into feedback that normally required a teacher. 61% completed the course, compared with a 22% category benchmark.

Concept as video, recorded against the same slide system.
(Solution 2)
2. One visual system, so nothing has to be decoded twice
Students were spending time figuring out the format instead of the concept. I made colour carry meaning: blue for instruction, yellow for practice. One slide anatomy, six tokens, and eight components created a repeatable system across 111 pieces. The system wasn't just for visual consistency. It allowed a two-person team to produce the course without reinventing the experience for every topic.

3. One course, whatever screen she has
Once the course no longer depended on a classroom, distribution changed completely. I designed the system around the devices students actually had: 18px body minimum, no custom fonts, and a reading order that held at any width. The same slides became a printed workbook and the video lectures were recorded against them. One learning system, four surfaces.
The same topic on a tablet. Reading order and topic number hold at any width.
500 paying students turned a 20-seat classroom course into a $90K online product, generating 4.7× the sales of one classroom batch. 61% completed the course, vs. a 22% category benchmark.

"Rachana built our entire design system and course herself. The lessons, the slides, the video lectures, everything. She has a way of breaking an idea down so a student actually gets it."
