Incoming EBE first-year looking for second-hand Year 1 textbooks

Hi everyone! I’m starting Economics and Business Economics (EBE) at UvA this September and I’m trying to get my books sorted without paying full Pearson prices.
If you’ve finished your first year and still have any of these lying around, I’d happily buy them off you:
• Sydsæter & Hammond – Essential Mathematics for Economic Analysis
• Perloff – Microeconomics
• Blanchard – Macroeconomics
• Harrison/Horngren/Thomas – Financial Accounting
• Newbold/Carlson/Thorne – Statistics for Business and Economics
• Berk & DeMarzo – Corporate Finance
Condition doesn’t matter much — notes and highlights in the margins are honestly a bonus. Also fine with ebook versions if you have a legit way to pass them on.
A few questions for those who’ve done Year 1:
1. Which of these did you actually need, and which did you barely open?
2. Do the courses still use MyLab for graded homework (i.e. do I need a new access code anyway)?
3. Is an edition older than the current one workable, or do the problem sets not match?
I’m in Amsterdam from late August and can pick up anywhere in the city, or from the E&B building. Thanks a lot, and any general Year 1 advice is welcome too!
