I find it very difficult to deal with Solid State, especially memorizing the values. Can you help please?

@ ajs 
Solid state are a very important chapter considering physical chemistry in competetive exams , and that chapter is very simple i think , which value u are difficult to learn ?? 
kindly mention the name , i will help u in the shortcut , 
there are some common value , like avogadro number , the value of coordination number , and the value of z for fcc , bcc and simple cubic , u can even work that out with a diagram rather than remembering the value , 
and abt that types of crystal and bravais lattice , no need to learn that table . 
thats nt as such required in any exam , u just need to remember the value of some packing fraction and density formula , and the property of diffrent types of solids , 
HOPE IT CLEARS YOUR DOUBT 
KINDLY MENTION WHICH VALUE U ARE FACING PROBLEM ,
