I done B.Sc. MCA and I am a software engineer, now I am interesting to learn law in distance education at Tirupati. Need some guidance.

Law through distance is not available. It is a full time course. Even if someone is providing any such course it will not be recognised by the BCI. You are eligible for a 3 year law course. So you can give entrance exams for GLC or take admission in a private college.
