-  - Sorting lists
-  - Reversing lists

+* Objectives
+  At the end of this tutorial, you will be able to,
+
+  - Concatenate two lists.
+  - Learn the details of slicing and striding of lists.
+  - Sort and reverse lists.
+* Pre-requisite
+Spoken tutorial on -
+- Getting started with Lists.
+* Exercise 1
+  Obtain the primes less than 10, from the list  ~primes~. 
 * Slicing
   #+begin_src python
     p[start:stop]
   #+end_src python
   - Returns all elements of ~p~ between ~start~ and ~stop~
   - The element with index equal to ~stop~ is *not* included. 
-* Question 2
+* Exercise 2
   Obtain all the multiples of three from the list ~num~.
 * Solution 2
   #+begin_src python
     num[::3]  
   #+end_src python
-* Question 3
+* Exercise 3
   Given a list of marks of students in an examination, obtain a list
   with marks in descending order.
   #+begin_src python
     marks = [99, 67, 47, 100, 50, 75, 62]
   #+end_src python
-* Solution 3
-  #+begin_src python
-    sorted(marks)[::-1]
-  #+end_src python
-OR
-  #+begin_src python
-    sorted(marks, reverse=True)
-  #+end_src python
-
 * Summary
-  In this tutorial session we learnt
-    + Obtaining parts of lists using slicing and striding
-    + List concatenation
-    + Sorting lists 
-    + Reversing lists
+  In this tutorial, we have learnt to,
+
+  - Obtain parts of lists using slicing and striding.
+  - Concatenate lists using the ``plus'' operator.
+  - Sort lists using the ``sort'' method. 
+  - Use the method ``reverse'' to reverse the lists.
+
+* Evaluation
+1. Given the list primes, primes = [2, 3, 5, 7, 11, 13, 17, 19, 23,
+   29], How do you obtain the last 4 primes?
 
-* Thank you!
+2. Given a list, p, of unknown length, obtain the first 3 (or all, if
+   there are fewer) characters of it. 
+  
+3. ``reversed'' function reverses a list in place. True or False?
+* Solutions
+1. primes[-4:]
+
+2. p[:3]
+
+3. False
