Study technique is very personal, but the most important part is discpline. You must put in the work, and you must work at a subject area until you understand it (with help from the training provider if necessary). Therefore I would place an environment where you will not be distracted and regular self assesment as high prioritites.
If you feel you need any more personal help than distance learning can provide then get in touch (email address in my profile). I give private tuition, and know many others who do too, between us covering all subjects.
Best of luck!
