Every NEET UG aspirant's journey is different — different strengths, different gaps, different timelines. So why should the prep app stay the same for everyone? 

That's the idea behind Darwin. If you're new here: Darwin is a NEET preparation companion built for one job — turning scattered, stressful prep into a focused, data-backed climb toward your rank. Not another NEET app with a giant question bank and a "good luck." 

A NEET prep app that watches how you practice, tells you the truth about where you stand, and adapts alongside you as your NEET UG journey evolves — from Day 1 to the morning of the exam. 

We've spent the last few months rebuilding Darwin from the ground up. Today, we're re-introducing it properly — as three distinct experiences, each built for a different stage of your prep. Here's what each one actually gives you. 

Free — Meet Your Prep Partner 

Free exists for exactly one purpose: to let you genuinely feel how Darwin works before you commit to anything. 

Inside, you get a solid slice of the core experience — 1,500+ curated questions to get your practice started, a Daily Test to build the habit of showing up every day. 

Think of Free as the trial run — enough runway to understand Darwin's rhythm, without committing to the full climb yet. If you're a student who's still exploring what a "smart" NEET prep app even looks like, this is where you start. 

Basic — Built for the Focused Grinder 

Basic is for the NEET aspirant who already knows what they need: volume, precision, and the right filters — nothing more, nothing less. 

• 38,000+ Questions — Access to our entire question bank. A massive, curated pool to draw from, so you're never short on practice material. 
• Custom Test — build unlimited personalized tests exactly how you want it, subject by subject, topic by topic. Get full control on time limit and Q-count. 
• PYQ Filter — go straight to previous year questions when you're racing the clock in your final stretch. 
• Exam Readiness Index (Exam Level) — a real-time read on where you stand, overall. 
• StudyPal (Limited Access) — a taste of Darwin's AI doubt-solver, enough to get unstuck when a concept refuses to click. 

This is exactly the toolkit for the NEET aspirant hunting PYQs in the final stretch, or anyone who wants sharp, filtered practice without the full analytics stack.  

If your prep philosophy is "give me the right questions, sorted the right way, and get out of my way" — Basic speaks your language. 

Plus — Darwin at Full Strength 

Plus is where Darwin stops being a practice tool and becomes a genuine prep strategist — one that studies you as closely as you study the syllabus. 

Everything from Basic, plus the tools that turn raw effort into real strategy: 

• Filter — High Yield — every syllabus has the handful of chapters quietly deciding your score. This filter puts them front and center. 
• Filter by Difficulty — Sort questions easily, moderate, and tough, so you control the intensity of every practice session. 
• Second Attempt & Option Elimination Practice — If you mark a wrong answer, Darwin doesn't reveal the correct option right away. It simply tells you that option was wrong and lets you try again from the remaining choices — so you keep working through the question instead of the app just giving you the answer. 
• Daily & Deep Revision — Daily Revision reinforces mistakes from the last 3 days, so recent slip-ups don't turn into long-term gaps. Deep Revision goes further, using AI-driven insights to fix weak areas and past mistakes across your entire prep. 
• Complete Notes (All Topics) — Full access to concise, exam-focused notes across every topic in the syllabus, not just a curated slice. 
• Flashcards (Biology) — Rapid-recall flashcards built for Biology, designed for quick, repeated review of high-yield facts and terms right when you need a fast refresher. 
• Exam Readiness Index (Exam & Subject Level) — Darwin pulls together your accuracy, revision depth, and performance under test conditions into one honest number, tracked both at the overall exam level and broken down subject-by-subject, so you know exactly where you stand and where the gaps still are. 
• PrepDNA — PrepDNA uses mathematical modeling on your practice data to assign a readiness score and percentile across subjects and sub-topics, weighing question difficulty rather than just overall accuracy. It flags your weak zones so you can prioritize the high-yield areas where your score has the most room to grow. 
• Adaptive / Personalized Practice — questions that recalibrate around your actual performance, and get sharper the more you use them. 
• Effort Analysis — Effort DNA is an AI-driven metric that measures the quality and consistency of your daily prep — not just how much time you're putting in — scored across four pillars: Weakness Practice, Deep Revision, Daily Revision, and Tests. It ensures you're practicing effectively rather than randomly, so your effort is actually translating into readiness. 
• StudyPal — your AI doubt-solver, on call whenever you need it, without limits. 

Plus is built for the aspirant who wants every possible edge working in their favor, every single day, right up to exam morning. 

Which Darwin Is Yours? 

NEET prep is long, repetitive, and honestly, a little lonely. Coaching classes give you content. Question banks give you volume. Almost nothing out there actually tells you where to focus next. 

That's exactly why Darwin now comes in three forms. Free lets you experience the app and build the habit of daily practice. Basic hands you the full question bank and precision filters — ideal if you know exactly what you're looking for. Plus brings everything together— every filter, every revision tool, and the complete AI stack — for the aspirant who wants a full strategist in their corner, not just a question bank. 

Different needs, different stages, same goal: your NEET rank. Pick the Darwin that matches where you are today.
