The discrepancy you observe between the reservation category mentioned in your candidate portal (Ezhava) and the seat type in the provisional KEAM allotment list (SM-EZ) can be explained by the way KEAM categorizes seats during the counseling process.

In the KEAM allotment system, **SM** refers to seats allocated under the **State Merit** category, which are open to all candidates based on their rank and merit, irrespective of their reservation category. **EZ** denotes the **Ezhava** reservation category. This means you have been allotted a seat based on your overall merit, but your Ezhava category is also reflected in the seat type.

Yes, you are fully eligible for reservation under the Ezhava category. However, in this instance, the allotment might have occurred through the State Merit list because your rank was high enough to secure a seat without needing to use your Ezhava reservation. In future rounds, if a seat under the Ezhava quota opens up in a higher preference course, you might still be allotted that based on your reservation eligibility.

Ensure you verify all details with the KEAM counseling authorities to clarify any doubts regarding the seat allotment process.
