Matrik is not the only way u can get scholarships abroad, it all depends on the current government and ministry of education, If they have a connection and get u scholarahips or not. U may score the highest and still not get scholarships if they don't get u one and it's not their responsibility to do so. Waiting on matrik for scholarships is not a good idea as u are relying on sth that may never happen and u are for sure wasting ur time if u are going to wait another year. If u really want to learn abroad and willing to male an effort for it try for scholarships in universities in USA u can apply through common app there.  I dont know the process for the others but u can know just google and u are willing to make the effort and if u are as smart as u claim u have a hogh chance of acceptance so i suggest u try applying.
