No you can not appear for the NEET as it requires to have cleared the class 12 with the subjects Physics, Chemistry and Biology with at least 50% aggrigate. So in this case you have cleared your 12 exam then you will not be able to appear in NEET unless you have passed with 50% aggragate marks. If you have 50% aggragate marks then you will be eligible fot the NEET. If you have got less marks then it will do for the exam but first I would like to suggest you that you first clear you physics and then appear for the NEET
