If I said je suis au college (ignore the missing accents pls) or j’en suis au college, Whats the difference in meaning and also can I even use the second one

It was along the lines of:

the rate of photosynthesis between 0-40degrees celsius doubles as the temperature increases by 10 degrees celsius (in the experiment listed in the exam). If at 5 degrees celsius, the rate is 2 arbitrary units, what will the rate be at 40 degrees celsius.
