Tips from seniors

Hey seniors. I'm 18F, currently preparing for the upcoming NDA on April 12th. I'm planning to do a degree in physics as backup if NDA doesn't work out. I've never prepared for jee or neet. I took PCMB and passed in 2025 with 86% (CBSE). I took a drop.to prepare for NDA because it was my dream to get in the navy and as a female it's the only way I can get in by Permanent commission. I can only prepare for iat or nesta after my exam but after reading alot of comments by fellow jee redditors it feels impossible, they have such good percentiles and have been preparing for years, still it's really challenging for them. I want to know if it's really possible to prepare in sucha short period of time. my family would tell me to do engineering if i don't get into IISERs or NIISERs. You can be honest, ik the ground reality is very brutal. I'm quite stressed about all this too. Please help me
