CLAT and AILET are the two most important law entrance exams in India. One unlocks 24 NLUs, the other opens the door to NLU Delhi. This comprehensive comparison helps you decide your strategy — whether to focus on one or prepare for both.
The fundamental distinction is institutional. CLAT (Common Law Admission Test) is a consortium exam — a single test that determines admission to 24 National Law Universities across India, including NLSIU Bangalore, NALSAR Hyderabad, NUJS Kolkata, GNLU Gandhinagar, and 20 others. Your CLAT rank decides your options across the entire NLU ecosystem.
AILET (All India Law Entrance Test) is conducted exclusively by NLU Delhi. It is a standalone exam with its own registration, its own pattern, and its own merit list. NLU Delhi does not participate in the CLAT consortium. If you want a shot at NLU Delhi, you must take AILET — there is no alternative route.
Both exams test broadly similar competencies — English language, legal reasoning, logical reasoning, quantitative techniques, and general knowledge. However, the way they test these skills differs significantly in format, time pressure, and question style. Understanding these differences is critical to building an effective dual preparation strategy.
Key takeaway: CLAT gives you breadth — access to 24 NLUs. AILET gives you depth — a shot at one of India's top 3 law schools. Most serious aspirants take both, and the preparation overlap is substantial enough to make this feasible.
The critical difference is time. AILET gives you 30 fewer minutes for the same number of questions. That means 36 seconds per question versus 48 seconds in CLAT — a 25% reduction in thinking time. This single factor makes AILET feel significantly more intense and is the primary reason many students find it harder. Additionally, AILET GK is standalone (direct factual questions), not passage-based, so you cannot extract answers from the passage — you either know the fact or you do not.
The question of which exam is harder does not have a simple answer — the difficulty manifests differently across sections and depends on your individual strengths. Here is a section-by-section breakdown.
CLAT English is entirely passage-based. You read 400-500 word passages and answer comprehension, inference, and vocabulary-in-context questions. The difficulty lies in passage complexity and the inferential nature of questions. AILET English is a mix — some passages, but also standalone questions on vocabulary, grammar, idioms, and sentence correction. If your grammar fundamentals are strong, AILET English may feel easier. If you are better at analytical reading, CLAT English may suit you more.
This is where the exams diverge most sharply. CLAT GK is passage-based — you read a passage about a current affairs topic and answer questions from it. Even if you did not follow the news story, the passage gives you enough context to answer many questions. AILET GK is standalone — direct factual questions with no passage support. You need to know the answer from your own preparation. This makes AILET GK significantly harder for students who rely on analytical reading rather than memorisation. It rewards disciplined daily current affairs study over months.
CLAT legal reasoning is purely passage-based — a legal principle or scenario is presented in a passage, and you apply it to answer questions. No prior legal knowledge is required; everything you need is in the passage. AILET legal aptitude can include direct legal knowledge questions — fundamental legal concepts, landmark case names, constitutional provisions, and legal maxims. Students who have studied basic legal principles independently have an advantage in AILET that they would not have in CLAT.
These sections are broadly similar across both exams. CLAT logical reasoning is passage-based, while AILET can include standalone puzzles and arrangements. The difficulty level is comparable, but the time pressure in AILET makes even moderately difficult questions feel harder. Quantitative sections in both exams are relatively straightforward — basic arithmetic, percentages, ratios, and data interpretation at the Class 10 level.
Overall verdict: AILET is harder primarily because of time pressure and the standalone GK format. CLAT is more analytically demanding per question but gives you more time to think. Students strong in speed and factual recall tend to find AILET manageable; students strong in comprehension and analysis tend to prefer CLAT.
Your exam choice is fundamentally a question about institutions. AILET is your ticket to one specific law school — NLU Delhi, consistently ranked among India's top 3-4 NLUs. CLAT, on the other hand, gives you access to the entire NLU ecosystem based on your rank.
Through CLAT, you can secure admission to NLSIU Bangalore (ranked #1 by NIRF), NALSAR Hyderabad (ranked #2), NUJS Kolkata (ranked #3), and other top NLUs. The top 5-6 CLAT NLUs produce placement outcomes comparable to or better than NLU Delhi. NLSIU Bangalore, in particular, has the longest legacy and the deepest alumni network in Indian law.
NLU Delhi has distinct advantages: proximity to the Supreme Court, access to central government policy institutions, and the highest concentration of Tier 1 law firm headquarters in Delhi-NCR. Its placement record in corporate law is exceptionally strong. For students whose primary goal is corporate law in Delhi, NLU Delhi is arguably the single best institution.
The strategic implication is clear: if NLU Delhi is your dream school and your only target, AILET is non-negotiable. But if you want the safety net of options across India's best NLUs — and you should — CLAT is essential. Taking both is the rational choice for any aspirant targeting the top tier.
Yes — and this is the most important strategic point of this entire article. The overlap between CLAT and AILET preparation is approximately 80%. The core skills — reading comprehension, logical analysis, legal reasoning, quantitative aptitude, and current affairs awareness — are tested by both exams. A strong CLAT preparation programme builds all of these.
The additional 20% that is AILET-specific can be layered on top of your CLAT preparation without derailing it. Here is what you need to add:
Build a daily habit of studying 30-40 factual current affairs points. Use flashcards or a dedicated GK notebook. Focus on: appointments, awards, international events, legal developments, economic data, and science-technology. CLAT prep covers the analytical side; AILET requires recall without passage support.
Practise completing 150 questions in 90 minutes instead of 120. Start with untimed AILET-pattern papers, then gradually reduce your time. The goal is to build the instinct to spend no more than 35-36 seconds per question. Timed sectional drills are more effective than full-length tests for building speed.
Study fundamental legal concepts that AILET may test directly: basic constitutional provisions (Fundamental Rights, DPSPs, Amendment process), landmark Supreme Court cases (Kesavananda Bharati, Maneka Gandhi, Vishakha), common legal maxims, and basic IPC/CrPC concepts. A dedicated 30-page legal knowledge primer is sufficient.
From October onwards (2-3 months before the exam), take one AILET-pattern mock test per week in addition to your CLAT mocks. Analyse these separately — AILET mocks will reveal different weaknesses than CLAT mocks, particularly around time management and GK gaps.
The recommended approach: prepare for CLAT as your base throughout the year. Start adding AILET-specific modules — speed drills, standalone GK, and AILET mocks — from October or November, roughly 2-3 months before the exams. This dual strategy does not require twice the effort; it requires about 15-20% additional work on top of solid CLAT preparation.
If you decide to take both CLAT and AILET — which we recommend for most serious aspirants — here is a practical timeline and approach for managing dual preparation without burning out.
Both exams typically take place within a few weeks of each other, usually in December. CLAT and AILET registration processes are completely separate — you must apply to each independently, pay separate fees, and manage separate admit cards. Mark both registration deadlines in your calendar early; AILET registration sometimes closes before CLAT registration.
Foundation phase. Focus 100% on CLAT syllabus. Build reading habits, legal reasoning fundamentals, logical reasoning, and quant basics. Begin daily current affairs tracking.
Intermediate phase. Start taking CLAT sectional tests and full mocks. Continue daily GK — now start maintaining a separate notebook of standalone GK facts for AILET. Read about basic legal knowledge concepts.
AILET integration phase. Add one AILET mock per week. Practise 90-minute timed papers. Intensify standalone GK revision. Continue CLAT mocks (2 per week). Register for both exams if not done already.
Final revision. Alternate between CLAT and AILET mock tests. Focus on weak areas identified in each exam pattern. Manage exam-day logistics for both dates — travel, accommodation, documents.
The key to managing both exams is not treating them as separate preparations. Treat CLAT as the trunk and AILET as a branch. Every hour you spend on CLAT preparation directly helps your AILET score. The AILET-specific additions — speed training, standalone GK, and direct legal knowledge — are supplementary, not foundational.
The answer depends on your goals, your preparation level, and your risk appetite. Here are three clear scenarios to help you decide.
This makes sense if you want maximum NLU options across India and NLU Delhi is not a must-have for you. CLAT gives access to 24 NLUs including four that are ranked equal to or above NLU Delhi — NLSIU Bangalore, NALSAR Hyderabad, NUJS Kolkata, and arguably GNLU Gandhinagar. If you are comfortable with any top 5-6 NLU and do not have a specific attachment to NLU Delhi, CLAT alone covers all your bases.
Also consider this if your GK preparation is passage-dependent and you are not confident about standalone factual recall — the AILET GK section could hurt your score more than help.
This is a high-risk, high-reward strategy that very few students should follow. It makes sense only if NLU Delhi is your absolute and only target, you are exceptionally strong in GK factual recall and speed, and you have a backup plan if your AILET rank is not sufficient. Taking only AILET means forfeiting access to every other NLU in the country.
We generally do not recommend this approach unless you have a very specific reason for targeting NLU Delhi exclusively — such as family in Delhi, a specific faculty member, or a commitment to a research centre at NLU Delhi.
This is the recommended approach for the vast majority of serious law aspirants. You maximise your options — 24 NLUs through CLAT plus NLU Delhi through AILET. The preparation overlap is substantial enough that dual preparation does not require double the effort. You get two independent chances at a top NLU, which reduces risk significantly.
If you are reading this article and are serious about getting into a top 5 NLU, take both exams. The additional cost (AILET application fee) and additional preparation time (15-20% more) are trivial compared to the optionality you gain. Use your CLAT preparation as the foundation, add AILET-specific modules from October, and give yourself the best possible shot at the best possible law school.
Yes. CLAT is conducted by the Consortium of NLUs and AILET is conducted independently by NLU Delhi. The two exams typically fall on different dates, so you can register for and appear in both without any conflict. In fact, most serious aspirants take both exams.
AILET is generally considered harder due to the time constraint — 150 questions in 90 minutes versus 150 questions in 120 minutes for CLAT. Additionally, AILET includes standalone GK questions that require factual recall, whereas CLAT GK is passage-based. However, CLAT passages can be more analytically demanding. The difficulty is different rather than strictly higher or lower.
No. NLU Delhi does not participate in the CLAT consortium. Admission to NLU Delhi is exclusively through AILET (All India Law Entrance Test). You must register for AILET separately on the NLU Delhi website and take the exam independently.
Both exams have 150 questions with -0.25 negative marking. The key differences are: CLAT gives 120 minutes while AILET gives only 90 minutes. CLAT is entirely passage-based across all sections, while AILET has a mix of passage-based and standalone questions. AILET GK questions are standalone factual recall, not passage-based like CLAT.
CLAT scores are accepted by 24 National Law Universities in India, including NLSIU Bangalore (#1 ranked), NALSAR Hyderabad (#2), NUJS Kolkata (#3), and others. NLU Delhi is the only major NLU that does not accept CLAT and conducts its own entrance exam (AILET).
If you are already preparing for CLAT, approximately 80% of your preparation covers AILET as well. The additional preparation needed includes: building a strong standalone GK knowledge base, practising under 90-minute time constraints, and preparing for direct legal knowledge questions. Most students add AILET-specific preparation 2-3 months before the exam.
Start with CLAT preparation as your base. CLAT preparation builds the foundational skills — reading comprehension, legal reasoning, logical reasoning, quantitative techniques, and current affairs awareness — that are tested in both exams. Once your CLAT preparation is solid, layer AILET-specific modules on top, focusing on speed, standalone GK, and direct legal knowledge.
The AILET cutoff for the General category at NLU Delhi typically falls around 65-75 marks out of 150. However, cutoffs vary each year based on difficulty level and number of applicants. For reserved categories, cutoffs are proportionally lower. Check NLU Delhi official website for the most recent year cutoff data.
