@aroragaurav I can empathize with that. There is a good intro course here:

@jlampel and the other instructors are great going just the right pace for beginners and use Blender without fancy add-ons that you may not have, if they do use one it will typically be free and they show you how to install it to blender and walk you through using it. I have found these are some of the best tutorials out there for beginners with blender and I have done a lot of YouTube learning.
And a topic covered by @theluthier you will want to read regarding interior design and using blender here:

A few words of warning:
1 Blender is a powerful program and highly customizable for more than just modeling. Learning it is not going to come to most people in just 1 night or even 1 week (I’m talking noob to pro). But it will fit most any need out there with time and experience.
2. Blender is not an optimized CAD software like standard CAD softwares. It can do just about anything but if you are coming from AutoCAD I or similar then I can imagine your frustration. You have to do a few more tasks than in those programs because it was not designed as a sole CAD system.
All that aside. It is a free open-source amazing program. Just means you’ll have to roll with the CAD punches as you come across them. You may or may not find this is going to suit your immediate need.
