Dilemma between IISERs and CDS.
I'm 18yo, would be joining IISER this year probably. I am very passionate to go into the armed forces (army specifically) although as we know that getting selected through NDA or CDS is very challenging and now everyone makes it, nor is there any straight path to do so. Right now for college I have 2 options basically, engineering colleges (RVCE, MSRIT, etc) and IISERS, im making decision between these two on the basis of interest purely, as what would I like to do in my civilian life if I don't get selected, that'd definitely be into research field. Although if I select IISERS, I'd practically be killing my army route.
I'm 18 now when I'll be joining college, I have 2 more NDA attempts with me that I'd give in 1st year of my college. But here's where the problem starts, I can only apply for CDS in the final year of degree or after graduation. The BSMS degree is too long, by the time i'd be in my 4th year, I'd already be 22, and most people are involved in master's thesis project in their 4th year, sometimes people even go abroad for that. I'd graduate at 23 and the maximum age for IMA application is 24, so I'd have 1 or 2 attempts at most that too considering I go for PhD elsewhere as most people tend to do.
It's quite a dilemma, I have to chose between 2 things, if I leave IISERS for army route and I don't get selected, that be very disheartening as I would've left a college and career path for nothing and vice versa. I don't know if there's any way around it, it's not an easy decision to take, especially at my age. I can't take a BSc degree at the end of 3rd year without having to leave college as far as I have searched.
If someone can help me with this decision or been in my shoes, please I would like for your advice.
