I am about to take en exam on SCJP 1.4 in may , and then thinking to take and upgrade for 1.5, but since 1.5 is not beta anymore maybe I should reconsider taking 1.4 and start learning towars 1.5 straigt? what are your suggestions? is it really worth taking 1.4 first and then upgrade?
As said in other posts, it depends on your needs. As Tiger is quite different from SCJP 1.4 due to its new features: Generics, autoboxing, etc, you need to read much more than SCJP 1.4. In addition, currently there is no books focus on SCJP Tiger, and thus, you might need to read JLS instead of a single cert. book.
and if so anyone have Idea if I can trade my 1.4 voucher for 1.5 ? I am willing to add some money if they request ?
You dont need to short your 1.4 voucher and long 1.5 voucher, as the voucher is valid for ALL 310 prefix exams. So, you can use your current voucher to register SCJP Tiger.
