You may need a good foundation of calculus for Physics. Biology is a class that you really have to keep up with and not allow yourself to get behind.
You seem to struggle in your classes so you should dedicate more time than you normally would for each class lecture. At the beginning of class read that syllabus and understand the expectations. Meet the professor for office hours regularly. If there is a study guide that goes along with the textbook purchase it. Every week review all that was gone over in class and read the chapters for new material before it is covered in class. You really have to be self disciplined and take the class with full intention of passing and not dropping it. Strive for at least a B in your classes. Get yourself organized and order all the required reading material before the class starts and start going over it. The focus and motivation to succeed has to come from within you. Nobody can do that for you. Make a weekly study schedule and stick with it.
Your academic track record is not strong. Consider discussing this with your doctor as you inability to stay focused and complete tasks could be medically related. If so you maybe able to get some accommodations.
You have struggled in your prerequisite classes for engineering. Without a strong foundation you will not be able to advance to upper level classes in engineering and may have difficulty transferring to a four year engineering program.
Unless you make drastic changes in your study habits you will get the same results you’ve gotten in the past.
Really take the time to focus on your health and be proactive about it. Set weekly goals for yourself and at the end of the week check to see if you’ve accomplished what you had planned for the week. Don’t procrastinate when it comes to studying for your classes as that will only lead to poor results.
