Thank you, Yuhua. Hello, everyone. Welcome to Sunlands' third quarter 2022 conference call. Despite the macroeconomic uncertainty and shifting industry landscape, we delivered encouraging results in the third quarter with sequential top line growth, further bottom line improvement and increased new food and enrollment.
This achievement testifies to the effectiveness of our strategic initiatives to prioritize profitability and healthy growth. Amid the ongoing pandemics and uncertain macroeconomics, our third quarter net revenues came in at RMB 576.3 (ph) million, up by 3.8% quarter-over-quarter despite 3.3% year-over-year drop.
To navigate the macro challenges, we remain laser focused on cost optimization and the profitability rather than blind pursuit of school expansion. We adopted multiple measures to enhance our operational efficiency and streamline our organization during the quarter.
Due to our effective expense control measures and improved operational efficiency, we reduced our G&A expenses by 29.6% year-over-year and 4.7% quarter-over-quarter. This cost reduction initiative enables us to deliver on our commitment to creating additional shareholder value will sustained profitability.
Our third quarter net income reached RMB168.1 million, representing an 81.1% year-over-year increase and a 48% -- 46.7% quarter-over-quarter increase, demonstrating our organization's resilience during tough times like this. With a leaner and more efficient organization, we also further refined our product strategies in the third quarter.
We focused more on margin accretive programs and allocated our capital and human resources accordingly to expand our course offerings in those programs, leading to an optimized product lineup and a more diversified cost content.
Additionally, we leveraged our solid and convenient online teaching infrastructure and the learning resources to further refine our services, which has increased our user stickiness and the core selling opportunities.
Given this, we have transformed our student acquisition efforts, focusing more on users' lifetime value instead of investing heavily in marketing activities. As you may have seen in our earnings release published earlier today, our sales and marketing expenses declined by 23.9% year-over-year and 8.2% quarter-over-quarter.
And as a percentage of net revenues, sales and marketing expenses were down by 12.7 percentage points year-over-year. Despite that, our new student enrollment for the quarter rose by 44.7% year-over-year and 11.8% quarter-over-quarter, reaffirming the effectiveness of our business strategies. Turning to our learning programs.
Our professional certification and scale programs continued to grow strongly as evidenced by 91.3% year-over-year increase in new student enrollment, which drove gross billings to derive (ph) by 51.8% year-over-year. Net revenues generated by this sector also increased by 83.7% year-over-year.
This growth was primarily attributable to our efforts in expanding our core catalog to target diverse age growths as we start to capture the rising demand we witnessed for [indiscernible] skills and [indiscernible] courses during the quarter.
In the third quarter, pandemic associated lockdowns led to the postponement for transformation of certain qualification tests, affecting our exam preparation program for those steps.
Nevertheless, demand for our preparation courses for professional exams remain solid as intense career competition per, prompted working professionals to enhance their competitiveness or shopping their sales with courses from educational providers such as Sunlands.
In addition to courses for working professionals, we continue to develop new courses to satisfy other cohorts, learning and leisure needs. We are excited about what we are offering and we offer our students. As we have always been committed to helping to build a lifelong learning society.
We will continue to capture opportunities in these sectors to deliver more high demand courses and high quality services to our students. Thanks to our extensive course options, premium core quality and experience teaching staff.
We are pleased to see students across a wider range of ages adopting our platform as well as greater diversity in the course too. As a result, we achieved sequential growth in new student enrollments for our professional skills program for five consecutive quarters.
We are also glad to have played a part in helping our students achieve their learning goals, bringing them a sense of fulfillment. Going forward, we will continue to adjust our course offerings in this sector based on market demand maximizing our value by further contributing to our students' success and our society as a whole.
Next, our Master's degree oriented programs. During the quarter, the challenging macro environment, the pandemics and the competitive market dynamics continue to weigh on our performance in this category.
Due to macroeconomic weakness, some people may choose to delay their higher education plans and as the course for obtaining an MBA degree is relatively high compared to other sales improvement options. Meanwhile, the pandemic also prevented some people from pursuing overseas post-graduate education.
Lastly, market competition was increasingly intense with more industry players join this sector after the K-12 education industry reform. Taken together, these factors resulted in reduced demand for our master's degree oriented preparation costs leading to a decline in gross billings and student enrollment.
Before I conclude, I would like to mention that alongside our efforts to solidify our industry position with our existing learning programs. We have also been prudently exploring some other new business initiatives to drive our future growth.
We are conducting invest market research on those initiatives such as combining retail or commerce with core skills. By maximizing our strength as an education provider to expand our product and service portfolio, we look forward to enhancing our risk management and creating additional revenue streams while bringing more value to our students.
Looking ahead, we are confident that our proven business strategy and continued commitment to delivering premium and tailored courses to more students will help us navigate current challenges and achieve meaningful growth. That concludes Tongbo's prepared remarks.
With that, I will turn the call over to our Financial Controller, [indiscernible], to run through our financials on behalf of me..
