How to Prepare for Final Examinations - Article Example Before, the beginning of examinations, the student should set certain goals which he likes to achieve or reflect in the examination results. Subsequently, all the efforts should be made to attain those predetermined goals. The goals should be realistic ones. In other words, the student should never set goals which are beyond his capabilities. There are many students who struggle to get even the desired grades in the final examinations because of the unrealistic goals just before the examinations. It is difficult for an average student to achieve first grade even if he tries extremely hard during the final examinations. If he wants to achieve first grade he should begin his preparations at the beginning of the course itself. When it comes to preparations of final examinations, different students opt for different ways. However, there are some general principles which are followed by the majority of the students while they prepare for their final examinations. First, it is better to start examination preparations as early as possible in order to avoid problems later. Early preparations help the student to avoid stress and anxiety with respect to final examinations. Majority of the students fail to perform well in final examinations because of their anxiety and stress related to the outcomes of the examination. Self-assessment of the level of knowledge in each subject is the second step in the preparations of final examinations. Before the beginning of the preparations, the student should decide which subjects need more attention and which subjects need less attention since he is the only one who knows his mastery in different subjects very well.  Ã‚

The concept of peak oil has been devised to reflect scarcity Essay

The concept of peak oil has been devised to reflect scarcity associated with oil supplies. But surely the price of oil would be a more efficient indication of its scarcity - Essay Example In contrast to the peak oil concept, global oil production showed a decline from its peak point at 74 mb/d in 2005; however, after a short decline the figures rebounded, and in 2011 there were higher production of oil than 2005 (US energy information and administration, 2011). Peak oil is ascertained by taking into account extraction rates from each oil well, the predicted oil reserves, and total extraction rate of an oil field comprising of associated oil wells (Berdellà ©, 2011). Here the core contentious issue is that the concept of ‘peak oil,’ which had been devised to reflect oil scarcity, is an ambiguous indicator of scarcity. Instead, some economists content that oil prices prove to be a more efficient indication of the scarcity of oil. Various experts contend that oil scarcity is dependent on the rate of consumption, where constraints placed on supply side are based on product demands. James L. Smith in his research papers, using benchmark scenario, high growth scenario and low growth scenario graphs, proved that peak timing is inconsistent as an indicator of oil scarcity (2011, pp. 8-13). Observations revealed that during 2007-08 economic crisis, despite oil supplies not increasing, there was loosening in the oil scarcity factor, owing to low demand. The equation for supply-demand graph can be plotted effectively through the factor of pricing, hence making oil prices a better indicator for its scarcity. Natural oil does not have any uniform or any standardised quality, and tends to vary significantly, which range from medium quality oil, to oil with high API gravity (high quality) from Saudi Arabian fields, to low API gravity (poor quality) heavy oil from fields in South America and Canada. Despite reports of fall in high quality oil levels, as far as supply of heavy oil is concerned, there is no scarcity, and many oil fields in deep-water areas remain unexplored (Stier, 2008). The Saudi Arabian high API oils are relatively easy to extract and oil
