hi abhay just weigh both the options and consider taking a decision only after weighing the options. if your current boss gives u adequate leave and the office timings are normal and ur current boss allows u to attend classes because as far as i know if u undertake industrial training then u have to work for atleast 10-12 hours a day which may not be the situation with your current boss.
Also min period of industrial training is 9 months so if i presume u join them on 1 st may,u need to give ur boss 1 months notice for that,then 9 months comes down to january and if ur ca final exams are in may 2011 then there is trouble.However if it is at a later date then may be its not an bad option.
Yes i agree the exposure u get in industrial training is far more than in a small ca firm but u have to consider the cons discussed earlier.
Slso consier the travelling time since most of the industrial centers are located in the city area.
Think properly and then take a decision because if u take a hasty decision it could mean trouble
I know other learned members may beg to differ on this issue but its my opinion and mind you clearing ur ca course is the ultimate
