You don't lose marks for not drawing the sketches, unless they ask you to do so in the question
I can probably help if you give me an example of a question you have a doubt in?

S1 is a very tricky but simple unit. Can you specify clearly what's your actual problem?

I'm glad I can help :)
Yea, we use the table
For example, if you have to find x and you have p(z<x), and you have the probability given, you could use the same table, and the value of z used should be the negative value of that given in the table
