It's easy but it took time to find the correct coordinates

```python
#!/usr/bin/python2

import requests, re
from PIL import Image, ImageDraw

def parse(html):
l = re.findall(r'

([^<]+)

', html)
ans = []
for i in xrange(0, len(l), 5):
options = map(int, l[i+1:i+5])
print "%s - [%s]" % (l[i], ', '.join(l[i+1:i+5]))
val = eval(l[i])
ans.append(options.index(val))
return ans

def solve(ans):
x, y, r = 362, 460, 24
img = Image.open("scantron.png")
d = ImageDraw.Draw(img)
for i in xrange(len(ans)):
sol = ans[i]
a = x+68*sol+(i/10)*(220+68*4)
b = y + 90*(i % 10)
d.ellipse([a-r, b-r, a+r, b+r], fill='black')
img.save(open("solution.png", "wb"), "png")

s = requests.Session()
url = "http://ee.sunshinectf.org/exam"
resp = s.get(url)
count = 1
while True:
t = resp.text
if t[:4] != '<h1>':
print t
break
print "Section", count
count += 1
ans = parse(t)
solve(ans)
resp = s.post(url, files={ 'file': open('solution.png', 'rb') })
s.close()
```
