Aid is helpful for the development of a country with regards to education etc. and you had to support your answer with 2 relevant examples. In the flurry of the moment, i thought of Pakistan and Somalia, both of which are receiving aid but aren't really growing. With hindsight, I think Somalia was not the best of examples... but ah well.
Know your Alevel Physics WELL. Read through a book of SAT 2 Physics. Make a formula sheet if necessary. Look at the AKU cirriculum and find the stuff you need to study (for example, the Michelson Interferometer, Black body radiation, etc). Once you've done that, look at the Inter Physics books and try to understand the concepts as much as possible. You don't need to go very deep with the details as its often hard to comprehend those mundane inter text books. What matters more is being strong in your concepts (being able to apply them to new questions) and being able to manipulate formulas and units with ease (a good mental-math ability is a plus).
Here is a link to a SAT 2 Bio book. I used Barrons, but content should be the same in this too.
So basically, once you've read all this, what you've got to do is.... STUDY! But once you've reached the limit and are finding it hard to sleep in the weeks or days before the test, with your mind getting nightmares of a tough test, with your hands often up in dua with regards to the test, or you just get sick at the prospect of studying any longer cuz you feel its pointless now, consider yourself ready for the test. Yup, you're done. Stressing yourself further won't help, because the majority of the paper is based on things you can't really prepare for in the first place. And in the end, whatever happens is the decree of Allah. Put your trust in Him and get a good nights sleep on the eve of test day.
Sorry for the loooong post again, but im sure this will help you. All the stuff in one place.
