I am scared to tell my parents my Regents grade?

so at the end of the school year, we took finals and stuff. and for math and science there are regents (for the classes i take). i told my mom about the regular final results i got. (which were like 97 & 98). on my earth science regents i got a 96. on my algebra 1 regents i got 89!! i was soooo disappointed! i studied soooo much for it! math is my worst subject. but being asian, i'm expected to have it as my best subject! and i'm freaking scared to tell my parents, so kinda sorta lied saying that the regents scores are gonna come in august. but i knew my scores already cuz the teachers had them (they have to put the regents grade into our averages). so if i bring up now that i actually do know the grades for my regents, wouldn't they yell at me? since i said idk the grades for them yet... cuz i'm willing to retake my algebra 1 regents in august, but for that i need to tell them! UGH IM SO TIED UP, what should i do??? see, the problem is, what if they don't take me in geometry honors nest year?? i need a 90 average for that!!! and my math average for 4th quarter was 90! so if i got 89, then i barely made it! idk if i even did make it!!!! OMG IM SOOOO WORRIED
