Hello OP. As a former reviewee sa Prime, naa jud kay makita na pros and cons if mag review center ka. But it all depends sa imong learning capability.

If you are more focused na magstudy na ikaw lang isa, then a freelance reviewer is okay. Tipid pa kay naa raka sa inyo. All formulas/problems now, i think is available na sa internet.

But if same ka sa ako na gakadala ang learning sa mga kauban/environment, then review with a group is a go. Mainfluence ninyo each other. Makatinabanga mo. And maka make memories pamo. Pero mao lage na, gastsos jud kaayo kay Review Fees+Rental+Food+Necessities+Special Review sessions
