if I get 160 marks in jeemains so i could eligible for addmission in L.D. collage ahmedabad.??

Hello.
As now there is percentile system in JEE mains so prediction on the basis of your score in JEE mains will give you result according to the previous system which will be a cause of big variation , so still according to the previous year records you are having good chances of admission bcz for LD. college , Ahmedabad if you have marks more than 120 then it is considered as good chances , but if we go with the previous year records of latest percentile system in JEE mains so in a more expansion if your common rank lies below 5000 (approx)  then your chances in top branches are decent but for other branches like biotech, civil, polymer science and lot more your rank must be under 22,000( approx), in percentile your percentile should be more than 99.000000 for top branches and 97.480000 for other less popular branches  but this calculation is on the basis of number of students appeared in the January session of exam it may fluctuate according to the conditions so your chances must be on the basis of percentile and rank you can see by yourself  with the help of provided data bcz on the basis of marks yes your chances are possible.
Best of luck.
