Hi Marie,
So you say you are interested in psych, so that's a plus you already have in your favor!

What psych class is this that your're taking now?
I also have issues w/ reading comprehension and attention, so I can relate.

What I did (and got A's in all of my psych classes) is set aside a couple of hours 3 days a week to devote to reading the assigned chapters. Highlight everything that is important & stressed during lectures. Do not cram everything into one long study session b/c you will not have time and you won't remember as much. If you've had Psych of Learning you'll know why already....
If you want an A, I suggest making note cards (flash cards) for all of the important concept/terms/theories. Write them out by hand, do not type them out. It may seem like a huge PIA but writing them out by hand helps you retain the info better. Then, study off your flash cards for a day or two before your exams. Doing it this way was a lot more work, but it worked for me. Also, make up acronyms for anything that will make remembering things like theories easier. Or use picture/story associations to help you remember things for your exam.
You CAN do it, you just have to make it a priority and eliminate distractions. If you have difficulty taking effective notes, maybe you can record your lectures or ask if you can access someone's notes. Your Univ may offer this through their Disability Office or you can see if Chegg offers notes for your class.
One other suggestion: see if there are any study groups avail for your class. That should help too.
Best of luck to you Marie! Please feel free to PM me too if you have any questions I can help you with. I

'ed every Psych class I ever took, but I still had to study for the A's...
