TNEA

For admission into Hindustan University, you need to write a separate entrance exam called HITSEEE. After that only you can get admission. It doesn't come under Anna University.

Right now, I hope you would be in a good college. So, it is not right to answer this now but I'm answering for the sake of others.
With this cut-off score, you cannot get any top colleges but some average colleges you can get. Look for a good one in the counselling.

It is just a single window counselling under Anna University which is for admissions into affiliated colleges under Anna University.
So, you need to appear for that counselling and there is no separate entrance exam for it. This year, the applications have been closed so that it is better to join a college with your marks or contact the admin if you wish to.

No, you need to submit all the attested photocopies within the specified application time. If you haven't received them, then you need to at least have a temporary copy of it.
Maybe you may ask the admin or at the time of counselling.

Hello Aswath,
You have a good cut-off so that you have medium chances of getting PSG Tech and low chances of getting Anna University CEG Campus. So you may try during the counselling. You can probably get the counselling on the first day with this cut-off.
For previous year's cut-off marks refer:

If you belong to BC category or MBC then surely you can get as the above-mentioned conditions are for general category.
