Is it good to do graduation from open university and simultaneously preparation for IAS?

Yes, it's a great idea to prepare for the UPSC while pursuing your graduate degree. Additionally, if you enroll in an open university, you will have the opportunity to prepare like a full-time aspirant, attending all classes, sessions, and workshops that are pertinent to the IAS preparation and experiencing the intensity of preparation concurrently.
Beginning early and acting like a beginner gives one the impression that they will receive supervision and assistance from a mentor, allowing them to jump-start their preparation and carry out all of the activities. So, anyone can do it, as I've seen a friend of mine who is in her first year of college search for the greatest platform that would enable her to make the most of her three years. After conducting a thorough search and survey, she discovered EDEN IAS.
For the modules and programs, they are offering in their foundation courses, this is recognized as the best coaching institute for IAS in Delhi. For instance, they were the first in all of India to launch LAKSHYA, a 3-year foundation course for IAS that was specifically designed for college students who were just beginning their preparation.
The reason their course is the best among the rest is that it includes all the essential elements, including modules on answer writing, current affairs, NCERT sessions, workshops on ethics case studies and UPSC essay writing, among many other things that will build an aspirant's foundation and advance them to the next level.
