Which section is difficult in SCJP syllabus?

[M K Rayapudi]

Dear Ranchers,
Which section/topic is difficult/confusing in SCJP syllabus?
If we consider all the candidates who scored above 90% (but not 100%), in which section most candidates are unable to answer?

Why I am asking this question is, If we know the difficult/confusing section/topic then we realize on which section we have to concentrate more.

Thank you.

It does not work like that. You will have to identify your weakness and determine where you need to concentrate your efforts

[M K Rayapudi]

thanks Deepak, I got you completely.
But my question is : For example, If we consider all the candidates scored 98%, these candidates did wrong with 1 question, someone may be wrongly answered in Threads concept, some other one may wrongly answered in Collections, etc.
In which section most people wrongly answered?

Different people find different topics difficult. I found Generics the most difficult during my preparation but I got one wrong answer and that was from the most basic topic "Declarations, Initialization and Scoping". I find garbage collection the easiest but people find difficulty in it. So its a matter of individual knowledge...

I lost most points on generics on the exam.
And while preparing for the exam I found generics and regex to be the most difficult part.

Having started the second round of reading K&B, I am finding objectives covered in Chapter 3 most confusing. Think these objectives will be potential pitfalls. There are too many minor details to make note of.

It is hard to gather that statistic but I ll help the cause and reply.

I found threads and generics a difficult nut to crack. In the real exam I took 2 thread questions and got 1 of them wrong. Most questions (>90%) about generics were answered correctly

The most difficult is what use less day-to-day.

For me, the most difficult thing, until now, is memorize the methods of the collections' classes, because I normally use just List and ArrayList.

So the answer is obvious: you need to practice what you know less.
