Answer:
its so easy to bypass the free unlocks on course hero
just look up *algebra practice test with answers*
screenshot each problem with the correct answer
don't show the problem number in the photo
then submit every one as a different test to course hero
a 30 question test which takes like 5 minutes to submit all 30 questions individually will get you 5 free unlocks
spend 30 minutes doing coursehero instead of school and your basically done for the year lol
