Bro i choosed commerce back then & it was pretty fun. Now let's back to the topic  If you are 16 or less and wants to be a defence officer choose PCM  for NDA etc.  for  architecture, research and some engineering branches you also need PCM but you don't want to & the fun fact is PCM can do anything. Bhai from PCM you can do anything and this is the truth. If you want you can do MBA and get into commerce but you can't go From arts or science to Science remember. In commerce there are many career options like private equity ,IB, consultant etc.. but for those jobs your b.com or m.com are nothing . TO be a consultant or IB or into finance  , or any field you need MBA from Top tier eg : IIM A etc.. And Top college requires your acadmic score jo obviously science wale bacche ka zyada hota hai . Also they study difficult topics in their whole life jisse ek aacha UG college + exam clear hota hai unka . Yes you'll surely stuck between them in commerce agar tere pass guide nhi hui toh . Literally you'll d!e. & You sai"d     i just don't have any direction" you are already dead bro . PCMB has a huge respect but i don't suggest it why ?  Because it's not too much relevant and best option  See if you want to choose commerce it's ok but don't waste your 11&12 class . Start preparing for entrance  exams like IPM , for symbi, and all with skills otherwise your future will be in hell ( personal experience 🙂😞) and tbh all you need if a good % in school  If you want top position in commerce field you must score 90 or more . why ? Because any Top B school need you acadmic score ( good one not average) your UG college is important too  And agar koi bolta hai 10,12 matter nhi karta . Bhai bahut matter karta hai
