<p>What does it mean to be a 3rd and 4th form? Thanks I'm just wondering when reading posts.</p>
<p>In secondary school forms are grades. Third Form is 9th, Fourth Form is 10th, Fifth Form is 11th and Sixth Form is 12th. In JBS- Fifth Form is 7th grade, Sixth Form is 8th and Seventh Form is 9th grade.</p>
