 * Summary
-  You should now be able to --
-  - Slice strings and get sub-strings out of them
-  - Reverse strings
-  - Replace characters in strings. 
-  - Convert strings to upper or lower case
-  - Join a list of strings
-
-* Thank you!
+  In this tutorial, we have learnt to, 
+
+ - Obtain sub-strings and reverse of strings by using the index numbers
+ - Use following functions -
+    - ``upper()'' -- to obtain the upper case of a string
+    - ``lower()'' -- to obtain the lower case of a string
+    - ``replace()'' -- to replace a character by another one
+    - ``join()'' -- to join a list of strings with an operator
+
+* Evaluation
+1. Given a string s = "this is a string", how will you change it
+   to "this isn't a list" 
+
+2. Given the string "F.R.I.E.N.D.S" in s, obtain the string "friends".
+
+* Solutions
+1. 
+#+begin_src Python
+s = s.replace("string", "list")
+s = s.replace("is", "isn't")
+s
+#+end_src
+
+2. s[::2].lower()
