Hi, Really did not have a problem with any of the tests until the HDLS series only have these 3 left and feel like it's a whole new level. Before I used NCLEX comp and SG101 to study. Just the cardiology alone is overwhelming. All the different meds dx's it is just so much to comprehend. Already to the practice test got 57 on A and 59 on B, not very encouraging. Any help would be appreciated. Thanks
