2018 graduate here. Here's what got me through.
Going more into my own experience: I didn't have a meal plan after freshman year, and I moved off-campus after sophomore year. I only had to take one semester of summer classes, so for my other summers, I convinced my co-op employers to keep me through August (I was on the January-June cycle). I often worked as a TA when I was taking classes, and there was one semester where I did part-time work for a co-op employer.
I think that the viability/payoff of staying at Northeastern really depends on your major. Ideally, your co-op money will help you get through school and the experience/networking will help you quickly get employed after graduating. If the prospects don't look good, then I think it makes more sense to transfer instead of staying and taking on tons of debt.
Basic accounting from a lemonade stand really helps you get a basics understanding of accounting which is the language of business and makes the rest al lot easier.

Always helpful knowing a bit about finance. The above is an easy intro. Not sure the difference between the original book which I have and the "for entrepreneurs" version though that was just the first to come up on Amazon.

Leider sind einige Zahlenbeispiele in dem Buch falsch, und es gibt Rechtschreibfehler.
Der Inhalt ansonsten ist sehr gut.
I understand what you're going through. In Intermediate 1, there will be topics that you've learned in Intro to Financial Accounting, but they will be more in-depth of it.
All I can say is, read the textbook, write notes from what you've learned in the textbook, come to class every day to take lecture notes that your professor will cover (depending how good your professor is), and watch videos on YouTube that cover topics in Intermediate 1. Depending on the professor, you can also ask him for help on a problem or a confusing topic of the class.
I recommend Edspira on YouTube, because if you have any confusion on a topic in Intermediate 1 (like revenue recognition), chances are, Edspira has a video on it. Here's his channel: https://www.youtube.com/user/EducationUnlocked
You can also look up other videos that will help you understand confusing topics, too.
All of this will help you pass the class. Also take mental breaks; take naps, do a quick 5-min break while you're studying, and/or do other hobbies. Don't feel overwhelmed.
I once heard my adviser explain that Intermediate 1 is a make-it-or-break-it class for accounting majors--she wasn't kidding around. I barely passed that class with a C if it wasn't for the textbook and videos on YouTube, as well as taking mental breaks.
Hope this helps.
EDIT: If you need to refresh your memory on the foundations of accounting (such as your Intro to Financial Accounting class), I recommend getting this book. This book simplifies the principles of accounting with an example of a lemonade stand: https://www.amazon.com/Accounting-Game-Basic-Fresh-Lemonade-ebook/dp/B001U29UIU
You might want to check out a book called The Accounting Game: https://www.amazon.com/Accounting-Game-Basic-Fresh-Lemonade-ebook/dp/B001U29UIU/ref=mt_kindle?_encoding=UTF8&me= (Kindle version). It really builds things from the ground up, and assumes you know nothing about accounting. It is one of the first books I read on accounting before I started at WGU.
I am a CPA and I thought this book was fantastic:
Accounting for the Numberphobic: A Survival Guide for Small Business Owners (https://www.amazon.com/Accounting-Numberphobic-Survival-Business-Owners-ebook/dp/B00KVO2C4W/ref=sr_1_3?ie=UTF8&qid=1467693376&sr=8-3&keywords=accounting+for+entrepreneurs#nav-subnav)
