Hey,
We all know that without officially released cut-off details of NIT Calicut by its responsible authority, The Joint Seat Allocation Authority ( JoSAA ), we can't make any accurate comment about the precise cut-off details of your desired college for this year.
So we have to go through the previous year's cut-off informations to make any decision regarding your admission possibilities. That's why I would like to recommend you to check its official website ( https://www.nitc.ac.in/ ) or the link provided below:

So it'll be definitely too much clear for you also that inspite of being ST category student you don't have any kind of possibility to get admitted in this renowned institution with this performance through 15% AIQ . Because according to 2019's informations, the last qualifying rank of your desired stream, Electrical and Electronics Engineering for the students outside of its home state Kerala under ST category was 905 where in this year your rank is 7543 .
Though the cut-off marks vary depending upon several important factors like:
Still I don't want to give you any unreasonable hope in this regard because it's obvious that the cut-off rank can't be too much decreased from 905 to 7543.
But if your residential state is Kerala, then with this rank you can get any department in this eminent institution, NIT Calicut under your reserved (ST) category through 85% Home State quota.

However you've enough chances in top State Government Engineering colleges, hope that you've applied for State Level Counselling (like Punjab, Haryana, Telengana, Rajasthan, Maharashtra, Kerala etc) which already has started.
