Need help for some website which can make studies easier to learn?

I’m afraid I am unclear how old this student is and what kind of help you are seeking for her.
It could be your terminology means more in your country than it does here in Canada or the USA.

Here are some suggestions for what I think you’re asking:

Thinkwell (we use it for math and Prof. Burger is awesome!)

The Khan Acedemy (free)

The Art of Problem Solving

The Teaching Co. (we have the Joy of Thinking and The Joy of Math and they are wonderful videos).

I’ll post if I think of more.

Your question shows a gal who has made no decisions yet. She should look in fields that make her happy now. Search those fields by internet search. It is hard to give direction when one does not have a dream. Brainstorm and find a dream.

@Dr_Lawrence: My cousin is of 12yrs old and I had heard of websites which have audio- video graphics used foe better understanding of your doubts.

@tranquilsea: Thanks for you help…

@Mary: I will take your advice :)

I moonlight for an online company called Tutor.com From the little I know about them, they seem to be a pretty good outfit.
