Hi there, Thank you for stopping by this thread. I'm an engineering student rekindling an interest in Maths. I just love studying Maths in my free time (and sometimes it trespasses into my non free time). I have plenty of fantastic books on my iPad and it's really helping me. However, I have been reading a lot of different books of late and it's getting a little jumbled in my head. I'm getting the impression that I'm getting a lot of superficial knowledge and then forgetting it very quickly. So, I decided that I have to start taking notes. I think that maybe if I take notes and then revise them I will be able to review them often and will get more out of my learning experience. I have downloaded the Microsoft OneNote app. It's a neat app and allows you to maintain multiple notebooks. I plan on maintaining a notebook for every book I read. I just love electronic notebooks. You save so much paper, write faster, easier to maintain and so much moe neater ! :) So, now my question is how do I maintain notes ? I'm a bit confused regarding what I should write. So, if anybody could offer any guidance, it would be excellent ! Also, please tell me how to maintain notes for different kinds of books. For example, books on Maths History like "Journey Through Genius" and "Crest of a Peacock" will require different kinds of notes than a technical books like "Visual complex analysis". And, in all my recently acquired enthusiasm, I want to maintain notes for all of them ! Any help will be much appreciated ! Thanks and may God bless you !
