What is Coachingle and how does it work?

Coachingle is a free AI-powered study platform that generates complete revision packs — cheatsheets, MCQs, mind maps, flashcards, audio podcasts, comics, slide decks, and animated videos — from any topic in under 30 seconds. Type a topic like "Photosynthesis" or "Rotational Motion" and the AI generates 8 different study formats tuned to your exam pattern (JEE, NEET, UPSC, Banking, SSC, or CBSE boards).

Is Coachingle really free?

Yes. Every student gets 10 free AI-generated study packs per day with no signup required. That covers daily revision for most aspirants. Paid plans start at ₹10 for 24 hours of unlimited access, ₹149 for a monthly subscription, and ₹499 for a 6-month exam pack. There is no advertising, no data selling, and no paywall on core features like cheatsheets, quizzes, and flashcards.

Which exams does Coachingle support?

Coachingle has dedicated subdomains for 6 Indian exam verticals plus a global vertical: JEE Main + Advanced (jee.coachingle.com), NEET UG (neet.coachingle.com), UPSC Civil Services (upsc.coachingle.com), Banking exams including IBPS PO, SBI PO, Clerk, and RBI Grade B (banking.coachingle.com), SSC CGL + CHSL + MTS (ssc.coachingle.com), and study.coachingle.com for US/UK students preparing for AP, SAT, GCSE, A-Level, and GRE. Each vertical has exam-pattern specific features like sectional mocks, PYQ banks, and syllabus pages.

How is Coachingle different from ChatGPT or generic AI tools?

ChatGPT gives you text answers. Coachingle generates 8 different study formats from a single topic input — each one tuned to the specific exam pattern. For example, a JEE Main question follows the NTA pattern with -1 negative marking, while a NEET Biology question references the exact NCERT line number. The AI also tracks your weak chapters across sessions and adapts future content to your gaps. Coachingle is built for exam preparation specifically, not general knowledge.

Is Coachingle content NCERT-aligned?

Yes, for Indian exam verticals. NEET Biology questions link directly to specific NCERT chapter and line numbers. JEE syllabus follows NCERT Class 11 + 12. UPSC content cross-references official syllabus topics. CBSE board exam content is NCERT-first. For international exams on study.coachingle.com, content aligns with College Board (AP, SAT), Pearson/AQA/OCR (GCSE, A-Level), and ETS (GRE) syllabi.

Can coaching institutes use Coachingle for their students?

Yes. Coachingle offers an Institute Portal with two pricing tiers. Per-Student at ₹75/student/month includes core AI tools, basic analytics, and AI doubt solving — suitable for institutes with 50-5000 students. Institute Pro at ₹25,000/month base (plus ₹40/extra student beyond 500) includes full white-label branding, unlimited mock interviews, a private knowledge base for the institute’s own notes, automated parent reports, and batch management.

What AI models does Coachingle use?

Coachingle uses a multi-model architecture. Gemini 2.0 Flash handles most text generation (cheatsheets, audio scripts, conversational tutoring). OpenAI GPT-4 handles complex reasoning and Socratic dialogue for Snap & Learn. Gemini 2.5 Flash TTS generates two-voice podcast audio. Gemini image generation produces educational comics. Each format uses the best model for that specific job, not a single generic model.

Quadratic Equations Notes for CBSE Class 10 — Free AI Cheatsheet

Quadratic Equations is a guaranteed 5-7 mark chapter in CBSE Class 10 — typically a 1-mark MCQ, a 3-mark factorization problem, and often a 3-4 mark word problem. The standard form ax² + bx + c = 0 (where a ≠ 0) is the foundation, and every problem boils down to finding its roots using factorization, the quadratic formula, or completing the square.

The discriminant D = b² - 4ac is the single most important concept — it tells you the nature of roots without solving the equation. D > 0 means two distinct real roots, D = 0 means equal real roots (repeated), and D < 0 means no real roots. Our AI cheatsheet presents the discriminant-to-nature mapping as a single quick-reference card along with the quadratic formula derivation.

Word problems are where students lose easy marks because they struggle to set up the equation. Common types: age problems (present vs. future), speed-distance-time (boat in stream, train), geometry (area of rectangle), and number problems (sum of squares, consecutive integers). The cheatsheet covers all five categories with template equations and solved examples for instant recognition on exam day.

Frequently Asked Questions — Quadratic Equations

What is the discriminant formula for Class 10 quadratic equations?▼

The discriminant is D = b² - 4ac for the equation ax² + bx + c = 0. It determines the nature of roots: if D > 0 there are two distinct real roots, if D = 0 the roots are real and equal, and if D < 0 there are no real roots (roots are complex conjugates). This is a favorite 1-mark MCQ in CBSE boards.

What is the quadratic formula for Class 10?▼

The quadratic formula is x = (-b ± √(b² - 4ac)) / 2a. It works for every quadratic equation and always gives both roots in a single step. Use it when factorization is difficult — with practice, it becomes the fastest method in the exam.

How many marks is Quadratic Equations in CBSE Class 10?▼

Quadratic Equations typically carries 5-7 marks in the CBSE Class 10 board exam — usually one 1-mark MCQ, one 3-mark problem solved by factorization or the formula, and often one 3-4 mark word problem on ages, speed-distance, or geometry.
