WELCOME TO SMART LEARNING SERVICE.
Dear student friends, you are all aware that
since the year 2023, SEBA Board examination pattern has changed. Here all
subjects (except MIL & Elective) will contain 50% marks as MCQs. This is an
initiative which is taken from the Smart Learning Service to avail chapter wise
MCQs from subjects like Social Sciences, General Sciences, Mathematics and
English which are free for you. In this section you will get probale MCQs and
short questions along with answers from the chapter 2 of Geography: Environment
& Environmental problems under the subject Social Science. All of you are
requested to try this and it is obvious that it may contain typing or setting
mistakes. If any such anomalies found, may requested to send comments/messages
in the comment section for rectification.
Hope you will enjoy.
