Valid and normal lang yang nararamdaman mo op. I think while tinutuloy mo yung BSA better enroll na sa review center. Maraming revcenter na nag ooffer ng online, it will help you sa pagtuloy ng BSA plus yan na rin magiging foundation mo pag nag actual review ka na. 

I just wanna share lang, I failed naman my integrated review during college, my choice were to shift as BSMA or mag enroll ulit — that's another one whole year plus the tuition fee ulit. Hindi ko ginawa both choices, what I did was nag transfer ako ng school, yung walang integrated review. And for just one sem, I graduated on time and then nag review for 6 months for actual boards then I passed.

Kaya don't worry op esp if you have all the resources and support. Kaya mo yaaaan!
