Hi guygs, Is there any significant difference between pathoma 2013 Vs. pathoma 2015 edition? I have 2013 ed. with me and when I checked the total pages of 2015 ed. in pathoma.com ,, I found it to be same as in 2013 ed. ie.218 pages in total. So, does it make a big difference in doing 2013 compared to 2015 ed.? what major changes are there in 2015 compared to 2013 ed???I am starting with pathoma and need a very honest advice. PLs help.
