Hello,

From your profile it seems you belong to Maharastra, hence I assume it's MAH CET LAW for three years LLB, application form for this year is already closed in case you haven't apply before then you have to wait out for next year unless you're seeking other alternative option.

see when it comes to process of registration you need photography/signature in prescribed format, and you have to keep your marksheet handy to put the same in the application form, and you're just required to have scanned copy of any photo-id proof such as voter-id/aadhar card etc,  also keep your application form/receipt/hall ticket carefully as these will be required for admission process.

check out the  information brochure of MAH CET LLB at https://admissions20.blob.core.windows.net/llb32022/dtefiles/files/15.pdf?did=2299 to know more details regarding this.
