Hi Roshan,
There are NO exam guides for the SCMAD examination. What is available in the market are books on
Java ME. I don't think there will be a exam guide kind of a book soon like Head First. Just download the specifications, and try to get hold of a good note set to study for the exam (MIDP spec has 500+ pgs). Sathyas' notes are good, but you have to add some more into it. I used this stratergy to pass the exam. BTW, I guess if you are very serious about SCMAD, you have to purchase a exam simulator as well. Regards..
