I am happy I did it and I am happy it is over. 6 weeks of studying and worrying. I had a training in February and was postponing ever since. Finally I scheduled for end of July and started studying. Here's my short LL.

1) Schedule in advance and give at least 6-8 weeks to get prepared. It's not only about the effort, it is about the duration, at some age it just takes a while for the knowledge to nest in your brain and it was a case with me.

2) Do the test at the beginning to first, discover your grey areas, second to compare later how did you progress.
