Sir, I just want to know which JD Lee, original or the one adapted by sudarshan guha, is best for JEE Preparation?

@ pavin 
The one which is adopted by sudarshan guha , thats excellent one for preparation of jee , 
u will find many more examples related to jee level their , but the original one is written in some difficult language as they are foreign author , and u might find some difficulty in understanding them . 
and the original one also not contain some chapters which are there in JEE syllabus . 

HOPE IT CLEARS YOUR DOUBT // ..
