I've passed 10+2 with 89% & want to join in this profession but don't have speaking skills in front of others, can I join this course?

Hi, You definitely can. Good speaking skill is one of the most essential quality, nevertheless with good practice and hard work you can improvise on the same. All the best.

You certainly can, but the road may be more difficult both during and after law school. Good speaking skills in a general sense is a must-have attribute for a good lawyer.
