A Unit Test when i was in class XIth ( Science Stream )

After my matriculation we,my buddies at my house - 7members opted science stream as all had about an average mark. There was Commerce stream too. All other house members had gals of both commerce & science in their houses & were jealous of us coz all gals had a misunderstanding that BUJI’s use to take science stream. But me n my buddies were sad because we had no gal in commerce so that we had less chance of getting any news regarding their class. The night before the unit test we all 7 buddies use to sit jointly & study combined. There was a rule that time to switch off the lights at 10pm.One of the greatest disadvantage of our dormitory was that Vice Principal (VP) mam could see our dorm directly from her quarters if we don’t switch off lights :( But the other houses were lucky that they could switch ON lights till morning!
On the first day of unit test we had two subjects Maths & Biology. One of my buddy found something unfortunate in the question paper & we planned to talk regarding the matter at night.9th & 11th students use to stay together in a dorm, so we had no privacy to go through the unfortunate matter. But we buddies were well planned regarding the matter... two of us took the Biology question paper & others sat on their respective places & started preparation. I & one of the buddies who were engaged in the topic found that there was Chemistry Questions printed over the Biology Question paper of which the test is on the next day. We was so happy & was about to jump in excitement. It was tough to dig the chemistry questions, but since the topics were from Organic Chemistry it was easy to figure out. At last we got about 20marks questions :) We studied jointly the questions which were as usual so the juniors didn’t doubt us.Since some of our friends were in other houses we settle on to share the questions to other house gals too... after the unit test, we got the papers... All girls attained mark the range of 20-24 out of 25!!!!!!!
