Passing the JEE Main examination is not the end of the journey; the real game begins during the JoSAA counseling process. Often, a student with a rank of 10,000 fails to secure a seat at a top NIT, while a student with a rank of 30,000 is happily pursuing their studies there. You might be wondering: why does this happen? In reality, the mechanism behind this involves the *Home State (HS)* and *Other State (OS)* quotas.

**What is this 50-50 Formula?**
In all NITs across the country, the allocation of seats is divided into two categories:

**Home State Quota (50%):** These seats are reserved for students belonging to the specific state where the NIT is located.

**Other State Quota (50%):** These seats are open to students from the rest of the country.

For instance, if you appeared for your Class 12 examinations from Tamil Nadu, you would be eligible for the Home State quota at NIT Trichy. Consequently, you could secure a seat in Computer Science here even with a lower rank compared to students from outside the state (Other State candidates).

**How is 'Home State' Determined?**
This is precisely where most students make a mistake. Your 'Home State' does not refer to the state where you were born or where your permanent residence is located. According to JoSAA regulations, your Home State is defined as the state from which you passed your Class 12 (or equivalent) examination.

For example, if you are a resident of Bihar but completed your schooling in Kota (Rajasthan), your Home State will be considered Rajasthan—not Bihar.

**The Significant Disparity in Cutoffs**
At top-tier NITs—such as Warangal, Surathkal, and Trichy—there is a vast difference between the cutoff ranks for the HS and OS quotas.

This disparity becomes even more pronounced at NITs located in Delhi (NIT Delhi) or the Northeastern states (e.g., NIT Mizoram, NIT Sikkim). Students belonging to the Home State benefit from a reservation advantage within their own region, which helps to slightly alleviate the intensity of the competition they face.

**What are the Rules for IITs?**
It is important to note that this quota system applies exclusively to NITs and a select few other institutions; there is *no* Home State quota applicable to the Indian Institutes of Technology (IITs). Admission there is granted solely based on the All India Rank (AIR).
