I just passed P/1 this sitting. I must say that I was feeling just like you were in August and September---only two months before my exam--you have six months--remember this.
I used the ASM manual (an amazing manual) to study as well as ACTEX. My first two times through the explanatory material were rough . . I definitely had to work through the problems in the explanations and some were still a slight bit over my head. Remember that you can email Dr. Krzys' questions about any problems, and in my experience he will get back to you very quickly and do anything possible to help you understand, not simply get the answer to a question. Also, Dr. Krzys' offers great review seminars for the exams based off of the manual that you are using--its amazing how things tend to make sense after he verbally explains things--i would recommend this greatly.
Here's the link for the information about the seminars: [URL="http://www.math.ilstu.edu/actuary/exams/prep_courses.shtml"]
As far as reading the explanatory sections, the hardest part for me was simply sitting down and memorizing formulae so that the material in the random variables and multivariate sections made sense with less effort. Make flashcards--but don't just make them--use them EVERY DAY. Also, I found it useful, although a big pain, to make a table to help me memorize all of the distributions needed--not just the commonly used ones. I made one with all the answers and a blank one that I filled in almost every day (this was probably the most effective thing I did). Either make one, or PM me and I'll send it to you if you would like it!
If you feel that you would like more than the few problems that are in the explanatory sections to practice a specific set of information, I would recommend using ACTEX or another manual with the same setup. This manual has ten sections so the material is broken down more, and gives a problem set after each section of 20-30 problems based on the material given in a specific section. Although this was somewhat helpful in the beginning, I didn't use it after I had a basic understanding becuase the problems seemed extraneous or simply too easy, unlike the majority of Dr. Krzys' awesome manual.
Even if you don't feel confident about all the material--start going through a few of the practice exams. I learned more through going through the solutions than I did reading the material over and over (perhaps this was becuase I knew the explanatory material almost by heart after going through it numerous times) You might not do so great on some of the practice exams, but keep doing the problems until you understand them---and then do them again. Most importantly, if you do poorly on an exam, especially before April, don't get discouraged. It happened to me, and it will only bring a person down, for me to the point of giving up on studying for a week. Don't let this happen to you!
I hope this helps
