Investment Allocation Advice for Student Investor

Hi I am a student who just started working. And I plan to start investing in my Roth IRA account. Would it be good to contribute consistently for 50% FXAIX, 25% FZILX, and 25% QQQS. And also would it be good to hold some of MAGS and SMH in my brokerage account?

I will appreciate any advice you give! Thanks in advance! 🙏
