Need to learn to write by hand more neat and fast

I searched the internet for tips for writing both fast and neat for exams but only found a few tips on the internet, so I came here looking if anyone had any trade secrets they may be able to share.

If I can’t achieve this VCAA (the marking agency for my final year) could deduct points from me solely on being unable to read my handwriting

I have to acquire this skill before 4 weeks are up at which time my exam period will start

Thanks for you help
