I DO NOT claim or guarantee whether the answer written here is 100% accurate. If you feel something is not accurate or out-of-order, it will be a great help, if you let me know. You know how to find me. Note: Those question which is crossed (i.e strikethrough) refer to repeated question which has been solved/answered already.
Every time I make some changes in answer, I will change the version number too, so that easier for you to understand whether the note you have to download is updated or not.
I have also added the “Completion rate”, which determines how much answer has completed out of total questions.
Note: This site is under maintenance. I will update the site later. For now, go to this site where I have added some notes.
