Hi student,

Since you are just in first year so for now just focus on class course. Analise if class teaching is better than just everyday revise what taught in the class. or else after class just get the preffered book and study the topics taught on that particular day in class. Also check out if you not tired at the end of the day then try different outside course. Make time table but dont overburden yourself and end up doing nothing. Follow the time table and be self motivated.

Thank you

Hope this helps you

Good luck
