You passed class 12 in 2024 and got 271 marks in Physics, Chemistry and Maths combined. In KEAM exam, both your entrance score and your 12th marks are important. KEAM gives 50 percent weightage to the entrance marks and 50 percent to the marks you scored in PCM subjects. So, your total score will be calculated using both parts. If your KEAM entrance marks are also good, then your final rank can be decent. Even if you are short by 27 marks in board exams or if you feel low in some subject, the entrance marks can balance it a bit. But KEAM does not allow direct mark changes or reductions after submission. So, the marks you got will be final, unless there was any revaluation done by the board.With the combined score, you can still get admission into many good engineering colleges in Kerala. Based on the past cut-offs, students with similar marks have got Computer Science, Electronics or Civil in private self-financing colleges and some aided colleges too.
