Want to do lawyers practise in high court

First of all decide what you have to do, either software engineer or lawyer.  Legal field is an ocean.  You have to dedicate your whole life to it.  When you have chosen to take legal field, you should not have any other avocations and engagements except law.  Still if you want to proceed with law, the procedure is as follows. 

Keep concentrate on your studies only.  After completion of the complete 4 years period of LLB, join with an Senior Advocate who is having atleast 25 to 30 years standing in civil law preferably from lower court.  The foundation of law will be learnt in lower court only and not in high court.  The trial, chief, cross will be done only in lower court.  Atleast you should do juniorship for 5 years.  During these five years keep collecting cases of your own.  After than you can become independant lawyer.  Even after becoming independant you will not get the cases so easily.  Again you have to struggle further more 5 years to get the cases.

The earning stage will come lately in legal field, whereas in software engineering profession you will get result quickly.  In the long run legal field is good.
