+* Objectives
+  At the end of this tutorial, you will be able to,
+
+ - use the ``for`` loop
+ - use the ``while`` loop
+ - Use ``break``, ``continue`` and ``pass`` statements to play around
+   with loops.
+* Pre-requisite
+Spoken tutorial on -
+- Getting started with ~for~.
+- Conditionals.
+* Exercise 1
   Write a ~while~ loop to print the squares of all the even
   numbers below 10. 
-* Solution 1
-  #+begin_src python
-    In []: i = 2
-    
-    In []:  while i<10:
-     ....:     print i*i
-     ....:     i += 2
-  #+end_src
-* Question 2
+* Exercise 2
   Write a ~for~ loop to print the squares of all the even numbers
   below 10.
-* Solution 2
-  #+begin_src python    
-    In []: for n in range(2, 10, 2):
-     ....:     print n*n
-  #+end_src
-* Question 3
+* Exercise 3
   Using the ~continue~ keyword modify the ~for~ loop to print the
-  squares of even numbers below 10, to print the squares of only
-  multiples of 4. (Do not modify the range function call.)
-* Solution 3
-  #+begin_src python    
-    for n in range(2, 10, 2):
-        if n%4:
-            continue      
-        print n*n
-  #+end_src
+  squares of even numbers below 10, which are multiples of 4.
+  (Do not modify the range function call.)
 * Summary
-  You should now be able to --
-  - use the ~for~ loop 
-  - use the ~while~ loop
-  - Use ~break~, ~continue~ and ~pass~ statements 
-* Thank you!
+ In this tutorial, we have learnt to,
+  - Iterate over a sequence using ``for'' and ``while'' loops.
+  - Break out of loops using ``break'' statement.
+  - Skip iterations using ``continue'' statement.
+  - Use the ``pass'' statement in a loop. 
+* Evaluation
+ 1. Given ``range(1,4)''; Write a code to print only the number 1.
+
+ 2. Which statement do you use to skip iterations.
+    - break
+    - pass
+    - continue
+* Solutions
+1. 
+#+begin_src Python
+for i in range(1,4):
+    print i
+    break
+#+end_src
+
+2. ~continue~
