Link. Curiously the filing is not yet available on sec.gov.
There are many sales, gifts of 4,500 shares, and one buy of 500 shares, with a net decrease in shares of 19,833. This is consistent with Pearson's analysis.
Proceeds were $59,619.93, quite a bit less than Pearson's claim of $138,831. Average sale price was $3.88.
I expect a similar filing for Ducon Technologies, though none for Saagar or Aron Govil, as I do not believe they have sold any shares.
Disclosure: I/we have no positions in any stocks mentioned, but may initiate a long position in CETX over the next 72 hours.
Additional disclosure: I was long CETX, but sold today.
