Two simple things for reading comp:
I see where you say "jotting down points" for reading comp. This can be helpful, but is best if you are doing it in a certain way. What you want to try to do, in effect, is to make each paragraph of reading comp into a short statement of the main idea. That way by the time you are done reading you have turned the reading passage into the equivalent of a critical reasoning paragraph.
So take down the main idea only. Do not write anything about the paragraph until you have read the entire paragraph. You are not really "taking notes" as this is very counterproductive. If you are writing down dates and figures and lists then you are veering too much toward taking notes. Stick to the main idea, stick to what is driving the passage along. Not to the small details. If a question asks about those details it is better to return to the paragraph anyway.
So that is the first point, take down the main idea of each paragraph - no more than 10 words or so. If you cannot come up with the main idea, then read that paragraph again. Do not force yourself through a passage that you have not been paying attention to...if you take down the main idea you will never lose focus for more than one paragraph. (Break really big paragraphs in two so they are manageable).
Secondly, and you may have heard this before, try to make yourself interested in the subject at least temporarily. If you can convince yourself that it is at least a little interesting, then you will be more able to pay attention. Pretend that you need to tell your friend about the passage in a just a few sentences...
