Hello aspirant

• your rank for KEAM  may be between 15 k - 25 k ,
• very less chance to get admission into CET College of engineering trivandrum  dream college of every keam aspirant
• there are chances to get into government engineeering college in last allotment , very little chace to get CS branch
• your probability to get admission in government and government aided colleges like TKM is very low still there is a chance to get admission through spot ( use spot admission very well there are cases in which 20k ranked students getting into government colleges through spot  admission )
• also try for government self-financing colleges like SCT ( SREE CHITRA TIRURUNAL COLLEGE OF ENGINEERING )and colleges under CAPE like college of engineering perumon , college of engineering muttatara as so
• you can also try many good private colleges

I will provide the link of keam rank and college predictor so that you can check in which all colleges you might get admission into ,so that accordingly you can prepare the list of colleges at the time of allotment
