Sir: As heat wave has already descended over Karachi, the city is facing outages of electricity. Recently on a workday there was a breakdown of electricity for about 6 to 7 hours consecutively and from that day load shedding of electricity is continued till date. Citizens also faced water shortage problems due to breakdown of electricity. K-Electric & other concern authorities should realize that these months are very crucial for matric and intermediate students as their board exams are about to commence by the end of the month of March. It is difficult for students to study in these circumstances. Students are future of Pakistan and being an under developing country those authorities which are concern with power supply in Karachi should try their best to provide favourable circumstances to students who are already tensed and depressed about their exams.
