A Level is undertaken after completion of Ordinary levels. A level courses are harder as compared to O Level courses and require more study hours and work effort to get a decent grade. As a result, students must choose these courses carefully and wisely and also take into account the courses which they took and studied during their Ordinary Levels.
For A Level students, there are no compulsory courses. Students can take several optional courses at a time but are strongly recommended to take only three if they plan to get good grades in all of the subjects. The minimum requirement even for the best universities is that you take three Alevels (excluding General Studies) The range of A level courses to choose from are vast and more perse as compared to O level courses.
Students are strongly advised to choose those courses which are complementary to the subjects they have taken in their o levels but it is not a compulsion.The reason being that in this way they will already be familiar with the course basics and know in which direction their academic pursuits are headed. However sometimes, if a student realizes that the courses taken in o level were not according to his aptitude, or if he failed to get a decent grade in his optional courses in o level, he may then choose a different area of study, and different courses so that he can improve his grades later on.
Some courses taught in A Level are double credit as well for instance law, and further mathematics. These are the courses which are relatively hard and complex and hence are accounted for as two courses.
Once a student chooses his A Level courses, he must pursue the same for the rest of his academic years as well as for the duration of his career. Hence, he must choose them wisely, in combinations, and with relevance to the courses taken in O Level.
Students can take up subjects from the list of subjects provided and in any best combination possible. There is no limit to the subjects being opted by a student.Every year Pearson Edexcel and Cambridge exam sheets declare which subjects are being conducted and offered in Pakistan. These are specified on the enrollment forms or registration forms.
In the event that an understudy is a private competitor, he/she ought to cross check with the enlisted subjects and regular school candidates ought to check which subjects are being offered at their school and in what combination.
