I have 58% PCM and 280 marks in keam 2019 .Will I get seat in any govt engin8 college

Hello Aspirant,
Your expected rank would be 37000, based on previous year's data.
Don't take this as the exact rank, as ranks may fluctuate depending on the difficulty of the paper for all those who attempted it.
With this rank, it would be quite difficult to get a government seat, but you may have a chance to get a seat after several rounds of allotment. Dont forget to apply for spot admissions after keam allotment as well, as many students having lower ranks get a seat in a good government colleges in the final spot admission. I'm saying this based on personal experience, as I study at a government college in Kerala.
You can also try admissions at the following private colleges in the meantime, as they are the best based on your rank:

ALBERTIAN INSTITUTE OF SCIENCE & TECHNOLOGY KALAMASSERY KOCHI

SAINTGITS COLLEGE OF ENGINEERING KOTTAYAM

SREE BUDDHA COLLEGE OF ENGINEERING, PATTOOR,ALAPUZHA

MALABAR INSTITUTE OF TECHNOLOGY,KANNUR

AHALIA SCHOOL OF ENGINEERING & TECHNOLOGY KOZHIPARA PALAKKAD

Good Luck!!
