Suggestions and advices

I just finished my 10th (got 88% kinda disappointed as I had 92% in 9th). I chose pre engineering in collage. Any tips for me especially for Urdu (my Urdu is super shit) and sciences. I got three main targets hoping to complete atleast one of them.
1)Nust
2)Abroad
3)Fast

Any advices for people who just cleared 1st year
