Hello,

That is upto you. You can use the downloaded softcopy version or choose for a hard copy.

If you get a soft copy the advantage is that it won't get damaged, you do not have to carry around many heavy books but require just your phone, save a lot of money, etc.

But Personally I prefer hard copies, since that gives me a sense of completeness when I study.

So both options are good, if you do not want to spend so much money on books then a soft copy will be just fine.

The important thing is that you use the study material properly and study well

Good Luck
