Measurement of Standard Model Processes in                                     
e+e- Collisions at 192-202 GeV                                                 
  
        Based on the analysis of about 200 pb^-1 of data recorded at           
        centre-of-mass energies between 192-202 GeV with the OPAL              
        detector at LEP, several preliminary measurements and comparisons      
        with the Standard Model expectations are described. In particular,     
        results on cross-sections for hadronic, lepton pair, and multi-photon  
        final states and on forward-backward asymmetries for the leptonic      
        final states are presented. These results are used to determine the    
        electromagnetic coupling constant alpha_em at LEP2 energies and        
        to put limits on new physics. Preliminary determinations of the        
        cross-sections for WW and ZZ production are described. QCD studies     
        of hadronic decays are also presented.  All results are consistent     
        with Standard Model expectations.
