Crucial ba ang Refresher Phase during Review?

Hello po! I am enrolled in TRA for FEB 2027 PNLE. Start na po ng Refresher Phase namin soon. However, nasabay siya na na-hire ako sa one month job lang naman.

Nauulit ba yung online class for refresher phase? Para sana after work ko nalang panoorin

Is it crucial pag hindi ko naattend-an real time ang refresher phase?
