med school is very different than undergrad. the cramming will definately not work here, it might jut get you by barely if you tend to cram for the exams. but cramming leads to the problem of not retaining any materials in the long run, which you would need for step1.
you would need to have the self control to study everyday. typically i avg studying seriously for about 6 hrs. when i say "seriously" i mean im not fooling around on the internet, watching movies or even having music in the background. all i have are the materials i need and want to study.
as far as what to use, that varies from class to class and from person to person. the best way to study in med school for any class, is to pre-read, attend lectures, post-read. so in one day you will have been exposed to the materials 3 times and then on the weekend, review, so in 1 week you should have at least been exposed to the materials 4 times. more exposure usuallyy will help in consolidation into long term memory.

and pre-read doesnt mean you read to learn and memorize the materials right away or even highlight the stuff! i see many ppl doing that andthey get frustrated b/c they dont understand the stuff they highlight. when you pre-read my suggestion is just to get the overall sense of the topic such as perhaps any new vocabs that you may need to know to understand the lecture/topic. and when you post-read then highlight the important stuff b/c by then you will have attended the lectures and should have a better sense of what is important to be highlighted.

and this point will be harder to do. many med students when they study, they tend to study just for the exams, which is obviously fine! but dont lose your focus of step 1 and that the materials in step1 will probably be more in depth and might have stuff that you didnt study for the "class exams"

study hard and learn each class well. it pays off. i have to say that b/c i learned all of the materials really well and understood the major concepts and points of each subject, pathology (which is usually the most dreaded class inn med school) isnt that bad to me. sure its volume overloaded, but all the other classes taught you the normal, and pathology is just the abnormal. so if you know the normal, all you have to do is to think in reverse sort of and pathology really wouldnt be that hard to understand.

as far as integration goes, that takes time. the more you know, the more you can integrate. its a skill that usually takes time to develop. but start doing it early. remember this, USMLE doesnt test and ask "what" the Qs ask "why" and "how". so start thinking along those lines as why and how does this work or not work. b/c everyone can memorize the key words for each disease or process, but do you really understand why and how it occurred? that is the whole process of learning medicine.

good luck!
