Most of what you want is available on the internet at different locations, but if you could buy a book or two that would really help, because you can study the book, and then use the internet for further research.

This is only a suggestion, but I think you could narrow down your studies, instead of learning all of 12th standard, try to dicsover what **specific areas** you need to know more about, and focus on those.

i'm donig MCA (Master in Computer Applications). there are so many math concepts which are required in computer programming. but i did maths only in 10th standard. its been many years. also, there are many concepts which are in my current cirriculum too, like, computer based numerical methods, differential , integration etc. etc. i really want to be comfirtable in maths coz it will help me all life in my field. please suggest me how should i go about it. thing is that, for my current curriculum, they assume i already know maths concepts of 12th standard. so, should i study maths of 12th standard now, or is there any website also which can make me learn math concepts like a book.

i'll really appreciate if i'm given help.

many thanks,
