Hello,
It's been more than 10 years since you passed your 12th examination in arts. I doubt if you are a graduate or have any specialisation in any field. See if so is the case then I would recommend you to look out for something else, Instead of repeating your 12 th again .
There are ample number of opportunities in humanities ( arts). You can definitely opt out for them.
But if you are really keen and inclined towards changing your stream and pursing your 12 th again in PCB then I would like to tell you , yes you can definitely go for it. You can do open learning. For that contact any near by school . It might help you. And just do reconsider your decision. And do check the age criteria for d pharma. I don't want you to regret in any way at the end..
Good luck and best wishes
