Biology is 360 of NEET’s 720 marks — half the exam, and the subject most aspirants lose the most marks on. We are India’s NEET biology specialist, delivering live online classes to PCB-stream students in 30+ countries since 2014. Same AIIMS-trained faculty, same NCERT-line-by-line study material, same weekly tests — now shipped to your home and taught in your time zone.
Free 60-minute demo class with Dr. Shekhar. Available in your time zone. Reply within a few hours (overseas timing respected).
Why biology is the rank decider
PCM = 360 marks across two subjects, scored well by most serious aspirants. Biology = 360 in one subject, and the one most lose marks on. Whoever owns biology, owns the rank.
Upfront so you can decide quickly without a sales call.
✓ What we deliver
✗ What we do not do
For PCM, our students typically pair us with school faculty, a local tutor, or one of the major online PCM providers. We can recommend partners on request via WhatsApp.
Two-way Zoom classes with real-time Q&A. Recordings available for any session you miss, but the value is in the live discussion and weekly mentor accountability.
Dedicated batch slots for Gulf (early morning IST), India (afternoon / evening IST), South-East Asia (evening IST), and North America (US-friendly window). Pick what fits your day.
Cerebrum NCERT-line-by-line guide + 12,000-MCQ chapter test bank shipped to 30+ countries. Tracking provided. Free with annual programmes.
Maximum batch size is 40 in our most affordable tier, 10-12 in our top tier. Every weekly test is reviewed in the next live class — the per-question discussion is the part that pre-recorded coaching cannot replicate.
Lead faculty is Dr. Shekhar C Singh — AIIMS New Delhi alumnus, 15+ years of NEET biology pedagogy, 680+ medical college selections including 67+ to AIIMS Delhi.
Your biology score trajectory is plotted week-on-week against the NEET pattern. Pinnacle tier includes a weekly 1-on-1 mentor call with Dr. Shekhar himself.
Pick the slot that fits alongside your school + PCM coaching. Final timings confirmed when you book a demo so we can match your daily schedule precisely.

PCB is the Indian academic stream — Physics, Chemistry, Biology — that NEET aspirants take in Class 11-12. This programme is designed for any PCB-stream student preparing for NEET-UG, whether you are in Class 11, Class 12, or dropper. Classes are live online via Zoom, with recordings if you miss.
We teach NEET Biology comprehensively — the entire Class 11 + 12 NCERT syllabus, every chapter, with NEET-pattern MCQ drilling. We do not teach physics or chemistry. Biology is 360 of NEET's 720 marks (half the exam) and is consistently the subject where most aspirants lose the most marks; our singular focus is on that. For PCM, our students typically pair us with their school faculty, a local tutor, or one of the major online PCM providers (PW, Allen Digital, Aakash Digital, Unacademy). We can recommend partners on request.
Yes. We run dedicated batches in multiple time zones — early morning Indian time for Gulf families, evening Indian time for South-East Asia, and a US-friendly batch for North America. Printed study material is shipped to your address (we ship globally; tracking provided). Doubt sessions are async on WhatsApp during your study hours.
Live classes have small batch sizes (10-40 students depending on tier), real-time Q&A, weekly tests with personal review, and a mentor accountable for your week-on-week progression. Recorded lectures don't know when you're falling behind. Per Dunlosky et al (2013) and Karpicke & Roediger (2008), retrieval practice and structured feedback drive learning — neither of which a passive video lecture delivers.
Class 11: ~6 hours/week of live biology + ~2 hours of weekly tests. Class 12: ~7 hours/week + tests. Dropper: ~10 hours/week + daily tests in the final 2 months. All slots are scheduled to fit alongside your regular school + PCM coaching. You pick the batch slot at enrolment.
Yes — we ship the Cerebrum NCERT-line-by-line guide, MCQ bank, and chapter test booklets to addresses in over 30 countries including USA, Canada, UK, UAE, Saudi Arabia, Qatar, Singapore, Australia, and Malaysia. Shipping included for our annual programmes. Tracking provided.
