I am in XI and seriously preparing for IIT-JEE and AIEEE (I am in CBSE). I want to inform all those who are preparing for competitive exams like IIT-JEE / Medical Entrance about a CD (set of 3 CDs actually - one each for Maths, Physics and Chemistry respectively) which looks first-of-its-kind in the market and at the outset looks good.
I first came across these CDs in Chennai. I thought that they would be the usual text-book stuff or mere question bank. But I was wrong when I saw the demos at https://anugraham.com (they have plenty of them). They contain professor lectures covering more than 1200 problems and 200+ theory pages. The 3 CDs put together contain 55+ hours of lecture covering all the topics in Maths, Physics and Chemistry.
I have now purchased a set (each CD costs Rs.600/- and a set Rs.1800/-) and am using it regularly. I recommend these CDs to all those who are preparing for IIT-JEE/AIEEE/Medical Entrance etc as an effective source of input to their existing arsenal. Whenever I listen to these lectures it feels I am attending a classroom course. Pause / Rewind / Forward controls are given to hear the lectures at our own pace of understanding which is an excellent facility.
The problems are graded and selective and covers most of the important concepts in all the three subjects. Have a look at the demos in their web site and if interested write / e-mail to them.
