Errors, teachers?

[Kenneth]

Hello teachers,

The sentence below sounds a bit weird altho I could not fathom out what is wrong with it. Could you please help?

"My result broke record to be the highest for the first time in 3 years in the history of the course I'm pursueing."

Thanks so much in advance. :)
Regards,
Kenneth
