38 CFR §21.7075

An individual who is entitled to educational assistance under 38 U.S.C. chapter 30 is also entitled to 36 months of tuition assistance top-up. This entitlement is parallel to, and does not replace, the entitlement to educational assistance available under § 21.7072. If the individual receives tuition assistance top-up, VA will make a charge against both the entitlement under § 21.7072 and the entitlement under this section. The charge will be as described in § 21.7076(b)(10).
