Hello Dear ,
I don't say you get admission in JEC or not because your percentile is not enough to get admission in JEC jabalpur. The admission in JEC is based on the cut off and cut off changes every year.But You give JEE main so you are eligible for the Jossa counselling .Do your JOSSA counselling and firstly fill those colleges in which you think to take admission.jossa counselling is started from 6 Oct 2020 .
Here is a jee main college predictor link:

After the jossaa counselling the seat in JEC is blank then go to JEC with CLC registration you definitely get admission.

Thank you
I hope this is helpful for you
