I have covered very good number of links in this blogs UCEED resource and book collections page for your convenience.  To help you with self evaluation and to check - to what extent these concepts really helped you with better understanding, I have decided to share some random sample questions quite often. Hope this self evaluation questions are of great help to you for your preparation :)

Evaluation question 1 :

Given below is a solid in 3D. You need to observe and answer the following (try to answer these questions without putting pen on paper !)

1. How many straight lines are used to form the solid ?
2. How many surfaces are there ?
3. How many rectangles, squares and other shapes are there ?
4. How many sharp edges (corners or points) are there in the picture ?

Now the same image is manipulated and is sectioned (cut) at the specified mark. Now, what will be the answers for the above same set of 4 questions ? try to imagine and answer without the use of pen/pencil.

Watch out for more practice questions !
