Yogesh Ajudiya.

Dr. Yogesh Ajudiya is the Founder and Director of The Phenol Institute and its sister brand The Catalyst Institute, now operating under Phenol School Private Limited in Rajkot, Gujarat. A first-generation Indian Chemistry educator, he holds an M.Sc. and Ph.D. in Chemistry, is CSIR-SPMF (NET) qualified with All-India-Rank 1 in CSIR-NET December 2015, and is also GATE, SET, GSET and GPSC qualified. Over the past ten years, he and the institute have placed 1,100+ students into MBBS seats with a documented 100% results record on the committed cohort.

The Educator — First-Generation, Self-Made

Yogesh's teaching career is self-made. A first-generation educator with no inherited institution behind him, he chose chemistry, chose Rajkot, and chose the slow compounding business of teaching school and college students for competitive exams. The first classroom was set up with a whiteboard, a stack of NCERT textbooks and the conviction that small batches taught well outperform big batches taught loudly.

Today the institute teaches Chemistry across four tracks — NEET, JEE (Main & Advanced), GUJCET / Boards, and CSIR-NET / GATE — to 11th, 12th, gap-year, drop-year and post-graduate students from across Saurashtra and Gujarat. The teaching philosophy is unchanged: concept before pattern, small batches, audit-grade weekly testing, and the calibrated honest mentorship that decides whether a NEET aspirant clears the cutoff or comes back next year.

The Mentor

Beyond the chemistry, Yogesh is the kind of teacher whose phone rings the night before the NEET exam — and gets picked up. The mentorship at the institute is not a bullet point on a brochure. It is the actual operating mode. Most of the 1,100+ MBBS placements over the decade share one thing in common: the student or the parent had a one-on-one conversation with the founder at the point where the year hung in the balance, and the conversation ended with a written plan, not an empty pep talk.

He engages directly with repeaters trying to break a plateau, with 12th-class students choosing between NEET and JEE, with M.Sc. students preparing for CSIR-NET, and with Gujarati-medium aspirants bridging the language gap to the English-language entrance exams. The door is open. The advice is free. The exam doesn't care whether the family can afford coaching elsewhere; the teacher shouldn't either.

The Founder · Phenol School Pvt. Ltd.

The Phenol Institute and The Catalyst Institute now operate under the registered entity Phenol School Private Limited. The institute is intentionally based in Rajkot — Saurashtra's largest city — rather than Ahmedabad or Kota, because the student pipeline, the cultural fit and the operating economics align around a chemistry-first coaching house in Saurashtra. The institute runs small batches by design, prioritises the weekly test review over class size, and has built every operating decision around what compounds across batches, not what scales fastest.

The Content Creator · YouTube

The institute's YouTube channel — THE PHENOL & THE CATALYST Dr. Yogesh Ajudiya — has nearly 10,000 subscribers and over 500 chemistry lectures available free. The channel exists because the classroom in Rajkot has a fixed capacity but the chemistry that holds up under exam pressure should be available to every student in Saurashtra, every student in Gujarat, every Gujarati-medium aspirant across India. Free chemistry, taught well, is one of the highest-leverage things an institute like this can do.

Programmes

The Phenol Institute offers structured Chemistry coaching across:

• NEET Chemistry — for medical aspirants in 11th, 12th, gap-year and repeater cohorts. The primary track that has produced 1,100+ MBBS placements.
• JEE Main & Advanced Chemistry — for engineering aspirants in 11th, 12th and drop-year cohorts, calibrated to JEE Advanced rigour where the student opts for it.
• GUJCET & Board Chemistry — foundational chemistry for GSEB / CBSE Class 11 and 12 students.
• CSIR-NET / GATE / SET / GSET Chemistry — mentorship for M.Sc. students walking the path the founder walked to AIR-1 in CSIR-NET December 2015.

Vision

A chemistry institute Rajkot can send any serious student to.

The goal is plain — to be the chemistry institute in Saurashtra that any serious medical or engineering aspirant can walk into and find the same teaching, the same testing discipline and the same mentorship that took 1,100+ students before them to MBBS. Quietly, year on year, without diluting the standard or chasing batch size.

Every cohort is one more set of students that proves the model works. Every cleared MBBS seat is one more family that knows the institute can be trusted with the year that matters most. Compound that across a decade and a half, and a chemistry institute in Rajkot can quietly become the one Saurashtra families default to when they decide to take the entrance seriously.

Operating Principles

The way Yogesh runs The Phenol Institute is anchored in six principles — the standards he won't compromise on, even as more batches join every year:

1. Concept before pattern — Chemistry is taught from first principles. The exam pattern is the application layer — important, but secondary. A student who understands stereochemistry will solve any NEET question on it; a student who has only memorised tricks will fail the first one the paper-setter rewrites.
2. Small batches, full attention — Batch sizes are deliberately kept tight. Every student is known by name, every weekly test is reviewed personally, every doubt gets a sit-down — not a queue. The institute scales by adding cohorts, not by inflating individual classrooms.
3. Test harder than the exam — Our weekly practice tests are calibrated harder than the real NEET / JEE paper. By exam day the student has seen tougher questions than the paper-setter is allowed to set. Confidence comes from the practice, not from a pep talk.
4. Show up, every class — The institute runs on attendance and consistency. The founder doesn't outsource the toughest topics to junior faculty. The lectures students need most are the ones taught by the person whose name is on the door.
5. Free chemistry, at scale — 526+ chemistry lectures are published free on the YouTube channel. A Play-Store app puts daily material in every student's pocket. The classroom does not scale; the chemistry should — and we make sure it does.
6. Open door for builders — An open door for the next generation of educators, M.Sc. aspirants targeting CSIR-NET, and first-generation families navigating the NEET / JEE system for the first time. The chemistry community in Saurashtra rises together — or it does not rise at all.
