Cambridge Proficiency C2 Prep follows the lead of the four Use Of English questions on the revised Cambridge® Proficiency Exam (Multiple Choice, Open Gap Fill, Word Formation and Keyword Transformation), to teach four C2 language skills. These are: - building and using collocations, including idioms and phrasal verbs - using grammar words including determiners and linking words - word formation, building different parts of speech - C2 paraphrasing using such structures as cleft sentences and causative constructions Each of the four sections of the app corresponds to one of the four exam tasks. Each section has eight units including notes, preview and practice activities. Sample exam questions are provided for each section. The app provides material for 30-50 hours of study and includes: - short (3 min) video presentations - tips about timing and marking as well as notes on language, meaning and usage - word building, editing and multiple choice activities - practice gap fill and transformation exercises - sample exam questions The app is designed especially to help students preparing to sit the revised Cambridge Proficiency® exam but will be of value to any Proficiency student.

Chemical engineering involves using physics, chemistry, and mathematics among other scientific disciplines to handle chemicals, raw materials, and even the food we eat. Chemical engineers are responsible for making sure the things we consume and use every day are safe and that the process for manufacturing is clean and as risk-free to workers and the surrounding community as possible. An understanding of chemical processes allows chemical engineers to design these systems. Some of the job entails problem-solving when things go wrong. Other requirements could include an intimate knowledge of environmental regulations. A chemical engineer understands these materials on a molecular level, giving them insight into the entire process from start to finish. Learn Chemical Engineering Chemical engineering is a highly sought-after discipline. A background or degree in chemical engineering can set you up for an in-demand and lucrative career helping design safety procedures, alternative energies, and sustainable energy solutions. Engineering programs can build those skills and give you the ability to break into this field. For many positions, a bachelor's degree and even a master's degree is required, but you can get started on that path easily. A chemical engineer's role is to maintain and structure projects by which the organic matter and raw material are altered to effectively utilise chemical substances. In recent times, chemical engineering is in huge demand owing to a large industrial number that relies on the processing and synthesis of materials and chemicals (Parra- Cabrera et al. 2018). The chemical engineers grab the deals and enjoy maximising opportunities in pharmaceuticals, biotechnology, and fabrication of electronic devices and engineering of the environment. In chemical engineering, block flow diagrams are mainly utilised to represent complicated procedures more than a single sheet. In this diagram, mainly mass flow rate is mentioned to discuss the balance of material over the point. The students or future chemical engineers are accustomed to distinct physical quantities' units which emerge under mass transfer, heat transfer, thermodynamics, measurement and fluid flow. Knowing the pump functions, and remembering all the constants that are dimensionless such as Nusselt numbers are some of the important facts that the candidates of chemical engineering must have the skills and ability to acquire. They must possess the skills of capturing the technical knowledge wholly and focus on learning the periodic table and elements' chemical valences. Derivations of some of the topics like Navier strokes, McCabe Thiele diagram, Kremser- Brown equation and more are important for a chemical engineer to remember for its future aspects.

Verdict
The clearest difference is review sentiment: Cambridge Proficiency C2 Prep at 50% against Learn Chemical Engineering's 0%. Learn Chemical Engineering's advantage is price ($3.99 vs $24.99) and update cadence (every 17 months vs every 39 months). On ads, in-app purchases, monetization model and device support there is nothing between them.
