Hello Aspirant

You can't get admission in COEP Pune through JEE Mains. For that you have to give MHTCET exam and since it is very tough to get into COEP you'll need to obtain about 180 marks to ge the branch of your choice.

Also if you are a non maharashtrian, you will only be eligible for the 15% outside Maharashtra quota and therefore admission will be even more difficult.

Nevertheless if you are planning to take MHCET and are not studying from Maharashtra board, I would recommend you checking out their syllabus as it is a little difficult from CBSE and other boards and that syllabus only comes in MHCET exam.
