Which is the best option to choose online or offline?

Hi...
I am Raji. I am preparing for IIT Examination. I am getting confused in choosing the mode of preparation that is online or offline?

 

You are probably asking a wrong question in the right forum

Ok..here's my 2 cents - online is Ok for taking timed practice tests but for preparation, I personally prefer printed books & material. The main reason is I won't be distracted as much as with connected devices. Again, this is my personal preference and YMMV. If you have the self-discipline to restrain from distractions, then it really doesn't matter.
