Hi Alok,
Well thanks for your appreciation !! 
I also appreciate the fact you clearly mention your difficulty.... This shows that you are more inclined to solving it rather than cribing about it..... So the first step of yours is absolutely right !!
Now comes, how should you go about with SFM..... !!
Firstly, accept in your mind that its NOT A DIFFICULT SUBJECT.... at all !! Its very scoring....!!
Open the practice manual and also Sanjay sir's notes (as you are referring to him).....
Now analyse by yourself, which is the chapter you are more confident in SFM.
Make an index as I suggested.... It would help you !!
Finance is a subject, in which the more you solve, better would be the confidence level.... I would suggest you to solve the examples of the book you are following !!
Bro, for you the most I can do is I can help you over CACLUBINDIA.COM itself.... !!
Since you are not strong in this subject.... I would suggest you to start with
1. Mergers & Acquistions !!
2. Divident Policy and further would let you know by monday how to go about with it
The time consuming chapters are
Capital Budgeting, Lease, FOREX and Derivatives to an extent
See Lease you can combine with Accounts (Accounting Standards)..... !!
Bro, I would too help you out with my notes, as how I made it easy.... Please give my some time.... I will have to get back to my notes..... !!
My Suggestion would for you to START with MERGERS and ACQUISTIONS today .... Solve it from Practice Manual.... and let me know if any difficulties..... I would try my best to solve it !!
Thanks !!
