Hello Kartikey !

It depends upon what other choices you have and what you want!

1. You aim corporate sector- No. No company visits here. Placement cell is a utopian dream at Faculty of Law.
2. You aim litigation- Yes. You will have ample time to nurture your skills. The Allahabad High Court and lower court will teach you the basics and make you pro.
3. Internships- Not many in Allahabad. However, you can always manage some of them under Judges, lawyers, HRLN and Mediation Centre.
4. You aim Judicial Services- You are most welcome. This is the right place for you. You can always manage your preparation since attendance is not strictly imposed, plus, teachers are easy-going. However, I won't recommend any coaching here!
5. Willing to enter student politics-Come dear! Allahabad University is the perfect place to learn all the bad things about politics. Here, you can learn Vote-Bank politics, hooliganism, vandalism and all sort of things necessary for being a good politician! *Sarcasm intended*
6. If you have to chose AU over any NLU or UILS, Punjab or UPES- Don't! You will regret it later.
7. If you think you will get great teachers here- No, you won't! We have lost the legacy!
8. Great Infrastructure- Five Year Law Course has awesome Classrooms. Rest everything is better, if avoided!
9. Library- Pathetic!
10. Cost-effective- Yes! It's meagre if you do a 3-Year course. Even FYL Course is inexpensive when compared to those of NLUs. Besides, fooding and lodging in Allahabad doesn't ask much.
11. Want Degree only- Yes, wouldn't cost you much of efforts here!

In case, you aren't aware, there are two undergraduate programmes run here: 3 Year LLB Course and Five Year Integrated Law Course. You have to make a decision.
