You can also explore colleges that accept JEE Main scores for admission.

Here's a breakdown of how you might be able to get into an engineering program in Kerala:

4. KEAM (Kerala Engineering Architecture Medical Entrance Test):

While you didn't qualify, you can still try to apply for KEAM, especially if you meet the eligibility criteria for Non-Keralite Category I (NK I). This category considers students who haven't traditionally studied in Kerala but may have other qualifications like studying in Kerala for a certain period.

Important Considerations:

College Research:

Thoroughly research colleges in Kerala, their admission criteria, and cut-off trends. Understanding their requirements will help you apply strategically.

Minimum Marks:

KEAM Eligibility:

If you're not a Keralite, ensure you meet the eligibility criteria for Non-Keralite Category I (NK I) to be considered for KEAM admissions.
