You need to clear JEE Mains with the valid cutoff to be able to stand for a seat in GSITS. Kindly go below the link to know the cutoff.

Now, you need to go through few rounds of JOSAA counselling similar to that of NIT's and IIT's and fill your desired choice. As you freeze your branch, you need to go for on campus verification and then you are admitted into the institute after few days of processing.

SGSITS Indore is not a private and government institute but is state government. Funded, supported but run by administered and maintained by private organisation. These colleges are called autonomous institutions which runs on both private and government interference.

Sorry, as with home state and your category, you need atleast 120 marks to be able to get into it this year which though your rank will not satisfy. I would suggest you to move for college level counselling after JOSAA counselling which may lend you something better.

With your marks, you'll not be able to get into GSITS with any of the branches as minimum you need is 145 with IP branch to get into it. You can only try in college level counselling which occurs to fill the vacant seats after JOSAA.

If you belong to General, along with home state quota, you need around 145 marks in JEE Mains or a rank around 35 thousand to be able to get a seat in it. Moreover, a better rank than these will reward you better branch respectively.
Best of luck.

You need at least 183 marks for getting CSE at least in the second round. In first round, the cutoff goes to 188 marks, though it is going to decrease this year as the cutoff has fallen down with a greater extent then the rest years. Hence, 175 would easily lend you CS for this year. Ranking should be below 23 thousand with home state quota.

You are not likely to get into SITS through JoSAA counselling through any round. Else, I suggest you to wait for the SPOT round or college level counselling where your marks may lend you something better in GSITS. The cutoff for the SPOT round is very less and you can easily get ECE or IT at 111. Also, it depends upon the number of seats, my data is according to previous year stats.
Best of luck.

With all India General Rank and without home state, you need at least 28 thousand rank and for other states, around 25 thousand rank to be able to get ECE. For EEE, around 32 thousand rank for home state and 28k for other states.
All the best.

You are too close to it. Last year, IP was closed at 141. This year, as the cutoff has fallen down a lot, you might be getting IP or civil easily, try for mechanical or chemical, but don't stretch for CSE and IT as you won't be able to get it through home state quota too.
Best of luck.
