I wouldn't say one year is easier than the other, as you're taking different classes each year so it really depends. However, there is a learning curve during freshman year since college courses are more challenging than what you might be used to in high school. So my biggest piece of advice would be to not be afraid to reach out for help during any year. Take full advantages of office hours that professors office and don't be afraid to ask for one-on-one time if their hours don't work for your schedule. Also, be sure to maintain a good balance between your work and social life. College offers a number of activities and events that you might want to jump right into all at once, but make sure you leave time to focus on your academics.
