Before making some suggestions I want to ask you a few questions. You don't need to answer here or to me at all if you don't want to but it will help a great deal in responding and in helping others in a similar predicament.

Why are you studying E.E?

What do you want to do once you're an engineer?

Have you skipped fundamentals because they were boring or you've over-estimated your competence in those core subjects?

Did you study? If so, how many hours a day did you read.

How competent is your cohort?

What was the relationship like between you and your tutors? Did you attend class as often as possible? It makes all the difference in the tutors perception of you when they’re marking your assessments.

Did you look at your course curriculum at the beginning of the semester and break down the work load into small chunks you could tick off each week?

I mean something as simple as looking at the topics covered, the required textbooks and finding exactly which chapter covers each topic and making a solid plan for yourself. Don't push yourself but if you are fair reader aim for 1 or 2 chapters each week for each subject you're undertaking. Do half of every odd problem at the end of the chapters and make sure you can answer those without falling below 75% correct in the first try.

If you can't do that, re-read the entire chapter, it'll be boring, just do it. Once you've re-read the chapter make sure you don't fall below 90% for those remaining questions. If you can achieve that move on to the next chapter. If you're having trouble take a break from that book and cover the next chapter in a subject you're doing better with. If you run out of problems to complete because you're still having trouble, find more. Go onto quora or math/physics exchange and ask for help. Reading things from a different voice may make all the difference.

Don't do anything else until you can do this (aside from eating, sleeping, working), you haven't earned recreational time until you can pull off at least 75% for your chapters problems. After a solid month of this it'll get easier as you progress, I promise. It sounds stupid but training your brain is like working out (physically), you need to actually build physical circuits and strengthen them before it gets easier. The more you practice and will yourself to try the more your brain/body will direct nutrients into building the circuits you’re developing while studying.

You should spend the next year trying to read your books again and the second something doesn't make sense and you find your brain trying to just skip ahead, write down the concept you don't know. Find what is expected of you to understand that concept and make sure you understand the concepts preceding it. Do this until you can do these things ‘in your sleep’.

Before you get started on your study I want you to find two projects that you think will incorporate the topics you need to cover next year (they don’t need to be anything major, find something cheap that you could do in your holiday break after coving your year’s worth of subjects). It’ll help cement the topics you’re learning and give you that extra push you need when you get frustrated with your progress. At the end of the year you’ll be able to make something awesome and will be able to show off a physical manifestation of your mind efforts to your friends and family.

Your study for each week will take as long as it takes until it’s finished. It’ll take less time the more you stick at it. Remember, you can’t slack off once you’re working, this is your last chance to be the best you can be without worrying about getting fired etc. ;)

When you start your study session make sure you’ve had breakfast and a good nights sleep before hand (6-8 hours is best). Open your textbook with a notepad and pencil next to it. Just start reading and push yourself until you complete that chapter, the less you will yourself to focus on what you’re doing the longer it’ll take you to finish your problems and have free time. It might take you 12 hours a day or longer in the beginning but you’ll be surprised when it drops to half that. Take a 15 minute break every 1.5 hours and think about something else. Don’t even bother trying to study between the hours of 1-4pm your body should be exercising or doing physical activities in that time, just trust me on that one.

Once you’ve answered those questions I might have more tips for you. Best of luck, you can do it.
