Hello Priyansh.
I would suggest you to first complete your graduation and then go for IAS since the minimum eligibility for IAS is 21 years. Till the time you complete your graduation you will be eligible to give the papers. If yet you are persistent on carrying on with IAS, I would suggest that you start your coaching from your third year itself since the burden is less and you get ample time to focus on your aim.
Hope this was helpful.
Good luck.
