Cerebrum Biology Academy runs live biology classes — not recorded video courses. Real-time Q&A with AIIMS-trained faculty, weekly tests with per-student review, English medium of instruction throughout. Live online classes serve 30+ countries in time-zone-matched batches; four offline centres in Delhi NCR (South Extension, Rohini, Gurugram, Faridabad) for in-person students. NEET, IB Biology HL/SL, AP Biology, MCAT, USMLE Step 1, Biology Olympiads, and CBSE/ICSE Class 11-12.

Three structural differences. (1) Specialisation: Cerebrum is biology-only; Allen/Aakash/PW are full-PCM. Our faculty don't split focus across three subjects. (2) Batch size: 10-40 students depending on tier vs 150-200 at mass-coaching. (3) Per-MCQ review: every wrong answer on weekly tests is discussed in the next live class — impossible at lecture-hall scale. The trade-off: we don't teach physics or chemistry. Most students pair Cerebrum biology with their existing Allen/Aakash for PCM.
Schedule varies by programme. Class 11 weekday evenings (Mon/Wed/Fri 5:30-8 PM IST). Class 12 alternating (Tue/Thu/Sat 5:30-8 PM IST). Dropper intensive (Mon-Sat morning 9 AM-12 PM IST). IB Biology HL/SL evening (Tue/Thu/Sat 6-8:30 PM IST). AP Biology in US-friendly time zone (Sat/Sun 8-10:30 AM US Eastern). Olympiad track (Sun + Wed). See full schedule below; we adjust for time zones at enrolment.
Live. Live is the entire point — real-time Q&A, weekly progress check, per-student review of wrong test answers, mentor accountability. Recordings are available for any session you miss, but the value is in attending live. We're not a video-course library.
Three tiers. Pursuit: 30-40 students (most affordable structured tier). Ascent: 16-25 students (most popular value tier). Pinnacle ZA: 10-12 students (direct Dr. Shekhar 1:1 mentor calls). Specific tier matrix shared on WhatsApp.
Both. Online live classes via Zoom from anywhere in the world (active student cohorts in 30+ countries). Plus 4 offline centres in Delhi NCR: South Extension (Delhi), Rohini (Delhi), Gurugram, Faridabad. Online and offline students share the same faculty and curriculum.
Yes. We have dedicated programme tracks for IB Biology HL/SL (2025 syllabus, Theme A/B/C/D coverage + IA + EE supervision), AP Biology (College Board score-5 calibration), IGCSE Biology (Cambridge syllabus), and A-Level Biology. Each programme has its own batch schedule + dedicated curriculum.
Yes — every class is in English medium of instruction. Study material in English. Tests in English. Doubt sessions in English (with Hindi or regional-language clarification allowed when a terminology word is the blocker). NEET, IB, AP, MCAT, USMLE, and all biology olympiads are conducted in English, so our medium of instruction matches.
