+# Tic Tac Toe Lab Assessment
+
+Everything's done--nice work!
+
+## Checkpoint 1
+Looks good. 
+
+## Checkpoint 2
+Works! I don't think there's a much more elegant way to do this, although I 
+might have chosen to separate out the data (row/col/diagonal indices) from the 
+looping structure. If you wanted to get fancy, you could do this (prob some constructs
+here you haven't seen, but might find interesting). Ask me if you can't figure out
+what's going on :)
+
+```
+combos = [
+    [0, 3, 6],
+    [1, 4, 7],
+    ...
+]
+is_symbol = lambda index: state['board'][index] == symbol
+return any(all(map(is_symbol, combo)) for combo in combos)
+```
+
+## Checkpoint 3
+Looks good.
