Top 9 Toughest Exams in India: Overview, Eligibility, Exam Pattern & Preparation Tips

Every year, lakhs of students spend months, even years, preparing for these exams, but only a few manage to crack them. This makes the question that much more important and confusing.

Is it the difficulty level of the paper, the cutthroat competition, or is it the extremely low percentage of people who manage to crack these exams that makes it “tough”? The answer, however, is that it is a little of everything.

Some exams test your concepts, some that test your consistency, and some that test your mental endurance. And what’s more, it’s interesting to note that the “toughest” of these exams is what differs from person to person, depending on what your skills and aspirations are.

In this blog, we will discuss what makes these 9 exams the toughest based on facts and figures, so that you know what you’re up against.

Why Are These Exams The Toughest?

When we talk about the toughest exams in India, we aren’t just talking about their difficulty level; it's about the strategies, guidelines, and how to manage them without getting burned out. Several factors decide how tough an exam actually is.

The first and foremost factor is the level of competition. For example, when we talk about exams such as UPSC, NEET, or JEE, we’re talking about lakhs of candidates applying across the country, competing for a very small number of seats. So, the level of competition plays a very important role in determining how tough an exam actually is.

The second factor is the success rate of the candidates who actually pass the exams. In fact, some of the toughest exams in India have a success rate of less than 1%. This clearly indicates that even if you’re well prepared for the exams, you might not end up passing the exams simply because of the low success rate.

Top Most Challenging Exams in India

There are several toughest examinations with specific criteria, levels, and levels of competition, and they require special strategies. Here are the top few examinations with less than a 1% chance of cracking, even after multiple attempts.

 UPSC (Union Public Service Commission) 

The UPSC Civil Services Examination is considered the toughest examination in India. It has the highest level of difficulty because of its low success rate and multi-stage examination process. This examination is held to select candidates for various top government positions, such as IAS, IPS, and IFS. 

Approximately, just 800-1000 students get shortlisted in the first stages of Prelims and Mains, out of 10-12 lakh students who appear for the examination. This makes the overall success ratio of this examination only around 0.1-0.2%, making it one of the toughest and most competitive exams in India. 

This examination is most suitable for those who can remain disciplined for a longer period and can handle uncertainty.

Why is UPSC tough?

In general, most UPSC aspirants spend approximately 5-6 years. Time is precious, and what if you fail? Doesn’t it feel so devastating? Can you rebuild yourself? Is UPSC your last life attempt, or do you have any alternative options? 

Most aspirants come from lower classes, giving their heart & soul, and lakhs of their hard-earned money to the UPSC preparation. After failure, some aspirants suffer from severe depression, societal pressure, and heavy debt. Additionally, in the worst-case scenario, they consider it as the last attempt at life.

Your 3 AM thought might be like, 'Was I not good enough? But what now? There is always a Plan B, which isn’t about giving up or losing your dream. You can gain new skills, pursue a new degree, or take an alternative path that helps you rebuild and protect your future and career.

You can think of it as a new way to social, emotional, and financial stability. These alternative paths assist you in gaining new skills and securing a good career path, so you don't feel your years are wasted.

Out of over 17 lakh students who take JEE Main, only 2.5 lakh are eligible to take JEE Advanced. Out of these 2.5 lakh students, only 19,000 get a chance to get into IITs. Thus, only 1 to 2 percent of students get selected to get into IITs.
