I'm at a community college right now taking classes. The four year university here has an articulation plan with my CC that let's student take classes concurrently in both the CC and the Uni. My question is: Is it OK to take summer classes (like CHM 2, PHY etc..basically the 'tougher' classes) at the Uni. while taking others concurrently in the CC. I'm a new immigrant and not in the best position financially. Thanks.
