i think this is bad:

int pGetCompleted[] =
{
    (ch->GetBiologState("biolog_lv92.completed")), (ch->GetBiologState("biolog_lv94.completed")), (ch->GetBiologState("biolog_lv92.used_window")), (ch->GetBiologState("biolog_lv94.used_window"))
};

if (pGetCompleted[1] != 1) {
    BiologManager::instance().SendUpdate_Binary(ch); }

if (pGetCompleted[0] == 1 && pGetCompleted[2] < 1) {
    BiologManager::instance().SendWindow_SelectType(ch, 1); }

if (pGetCompleted[1] == 1 && pGetCompleted[3] < 1) {
    BiologManager::instance().SendWindow_SelectType(ch, 2); }`
