Padala Rama Reddi Law College

Hello,
Yes, you can still get some college without qualifying for the exams.
You can prefer good private institutes as well.

The LLB 3-Year Degree full-time regular Course at PRRLC is offered through semester system to the students admitted as prescribed by the Bar Council of India. A candidate for admission to LLB semester course has to qualify at the LLB Common Entrance Examination (LAWCET) for that academic year. The candidates will be admittedly strict in accordance with the merit secured at the entrance examination.
So, LLB is a three years full-time course and a minimum of 75% attendance is a must for eligibility for end semesters exams. So, you can not get the privilege of not attending the regular classes.

No, law is a full-time course so better you do this course individually as BALLB or BBALLB.

Yes, go ahead. It is a great course to pursue.

The fee structure depends on college. You should directly contact college for the details.
