School is officially back in session, but according to a recent聽study from WayUp, a website for young job seekers, there鈥檚 one thing just as stressful as doing well in the classroom: your student loans. The study found that 60 percent of students find loans to be financially stressful. (Uh, how is that not 100 percent?)

With student debt rising by $3,000 a second, chances are, you鈥檙e likely part of the 80 percent of undergrads working during the school year. So if you鈥檙e going to pull double duty 鈥 in the classroom and in the workforce 鈥 you should know which jobs will get you the most bang for your buck. Insert Liz Wessel, the 26-year-old CEO of WayUp, who鈥檚 dishing on the most popular part-time jobs found on the site and exactly what makes them so enticing.

1. Sales/Marketing/Social Media Interns: Now more than ever, employers are looking for candidates out of college that already have real-world experience, so it鈥檚 no surprise internships in these industries are popular. Liz says, 鈥淵ou can get great experience with awesome brand-name companies and build up your resume. Often, Brand Ambassador and Sales Rep roles are popular because they are roles that students can easily complete on their own time and fit into their busy college schedules.鈥 She adds, 鈥淚n a sales internship, whether you鈥檙e trying to sell a product through cold-calling or trying to negotiate a job offer, being able to persuade others and help them see your vision is a crucial skill in any professional setting, and one that鈥檚 likely to make you stand out in a pool of other candidates.鈥

2. Barista:聽鈥淧art-time jobs like barista positions are popular because they award steady hourly pay, and offer an awesome group of co-workers on-site. Not surprisingly, Starbucks is our most popular barista employer,鈥 notes Liz. To which we say, um, obviously. Free frappes, anyone?

3. Freelance Writing: Experience on your own schedule? Yes, please. 鈥淎 lot of publications build out college contributor programs 鈥 like The New York Times, which has a great brand ambassador program where they hire college students interested in writing,鈥 notes Liz. She adds, 鈥淲hether you鈥檙e emailing a co-worker, writing to your manager or crafting a proposal for a client, your writing skills can easily boost or hinder your career, even if writing isn鈥檛 the main part of your profession. A quick typo or small grammatical error can easily weaken your credibility.鈥

4. Software/Engineering Internships: Sure, lots of engineering students can code in their free time, but why not get paid for it? Liz agrees, saying, 鈥淭hese roles are popular with engineering students because you can work on incredibly challenging or worthwhile projects where you are initiating and building things from your dorm room or the library.鈥

5. Tutor: Whether it鈥檚 face-to-face or online, tutoring is a great way to earn some extra cash. 鈥淭hese roles are popular because you are able to help your peers while making money and becoming an expert in your field of study,鈥 adds Liz.
